Title: 69 Boss 302 Disassembly
Post by: J_Speegle on May 28, 2013, 12:35:56 AM
Recently started the process of replacing the engine in my Boss that I've had over 20 years. Car has about 30K miles but has a body repaint :(  When I purchased ti we did the paint, freshened up the engine compartment and dropped in an engine I had rebuilt for a friend.  Finally found all the parts I needed fro the original engine, had it rebuilt and figured I needed to put them both together again.  As usual nothing is that easy, can't just drop the new engine in the old engine compartment and that front suspension is showing a little age (cleaned and cleared it years ago when I first got it) so you get the idea. Currently engine bay is being repainted, original suspension is out, being cleaned again and refinished if needed.

Will be repairing the drivers seat (just got a rear seat for a donor panel) and the antenna will disappear since we've since discovered it was a radio delete car originally

Purpose of this thread is to share some pictures of the original pieces, finishes and such in a hope that I can help someone else our provide a base for further discussions. Hope its helpful


For the record (I better not forget to include this ;)  this is a April 24th Dearborn built Boss 302

Thanks - no restoration this time - but must confess  its often difficult to stop yourself from going to far or too detailed :)

Spindles

Nice shape for 4 years old.

Worst looking of the two sides

(http://i44.photobucket.com/albums/f49/firetrainer/Boss%20details/9F02G188388/9F02G188388psspindle_zpsad971c60.jpg) (http://s44.photobucket.com/user/firetrainer/media/Boss%20details/9F02G188388/9F02G188388psspindle_zpsad971c60.jpg.html)



69 Boss/HD spindle identifier

Another angle

Quenching effect and coloration of the metal still visible after all these years. A little cleaner after some degreasing. You can make out the difference in finish on the steering arm where the original arm paint mark was located

(http://i44.photobucket.com/albums/f49/firetrainer/Boss%20details/9F02G188388/9F02G188388dsspindlefinish_zps1befcc74.jpg) (http://s44.photobucket.com/user/firetrainer/media/Boss%20details/9F02G188388/9F02G188388dsspindlefinish_zps1befcc74.jpg.html)



Close up of the darkened verses machined surfaces - Yes a little grease and chips - look much better after they were fully cleaned. Got to love those original Calif cars :)

Can't make that call. Know its been discussed over on the Boss site over the years and there seems to be a fair amount of 69' with the DO spindles (fair number of examples of DO parts used on cars originally if built during certain  time periods. Tie rods were replaced on that side (again only 3K miles on the car) but can't say that they are connected.

 Jeff, Typical Spindle for 69 Boss 302 has DOZA casting number. The Typical 70 Mustang with disc brakes also has DOZA casting # but different suffix. The bearing size is different and rotors are not interchangeable. The KKX spindle is common on 69 302, but not as Typical as D0ZA from my obsevation. Same thing happened on 69 Shelby's with F 60 option. Many items on 69 Boss 302 have 70 engineering numbers due to late year introduction.The Exhaust system intermediate pipes and resonators also have D0ZA engineering numbers. I can check the Engineering numbers later as we are heading to Carlise. I'm sure Ed has them written down as this is a 69 Shelby oddity also. Talk to you soon.

That's what I recalled but found it sort of self serving in this thread ;)

You guys have a safe and rewarding trip - leading a hand at the MCA show this weekend instead.

In my 69 Shelby meetings letters it says maybe 50 shelbys to get the new remachined (shorter) kkx 69 b9 spindles in late march as part of new HD f-60-15 tire option. So early 69 b2s would also get these being built around same time as shelbys changover to bigger heavy duty suspension.  I think jeffs b2 has original spindles on it as I have seen several shelbys with both re-machined kkx & new doza on same car & his has the double wire twist on them & that was assembly line ID & in 1970 assembly line ford used the green tape for ID.   The easy way to id the 69 1/2 Shelby & b2 spindles from the regular (all 1970) disc brake spindles when installed on car is to look at the cast metal rib (with hole) just below cast ID # kkx or doza on jeffs picture & notice the way it is cast as the rib is thin & tall with hole  but in 1970 & up the spindles have flat & wide rib below casting doza #s. Later on in 69 production the doza replaced the kkx (early remachined shortened b9) spindle.

Getting ready to put the engine compartment black back on (not restoring just freshening up)  and I thought I would show the factory markings I found on the radiator support. I hesitate doing this (since I don't want people copying them) but I hope this motivates others to take the time to look to see what their cars have.

This car is a spring built 69 Dearborn car

These are the marks we sometimes (depending on plant and production year) find on the radiator support. They appear to have been applied to the bare steel as helper codes for other workers and painters who would later cover them with paint. It appears that the wax based crayons were absorbed into the metal and often are still there today if our cleaning methods are careful and we take the time to seek them out.

Sometimes the coding is fairly straight forward - things like first rotation number, exterior or interior color codes are found. Sometimes the coding is not understood so we just document so that if one day we done gain a greater understanding we have the information

Passenger side - Pretty straight forward exterior color code of "3" and a first rotation number that starts with the letter "A"

Letters and numbers were highlighted in paint by me so I could document the markings

(http://i44.photobucket.com/albums/f49/firetrainer/Boss%20details/9F02G188388/9F02G188388radsupportmarks1_zpsa7e3ba2d.jpg) (http://s44.photobucket.com/user/firetrainer/media/Boss%20details/9F02G188388/9F02G188388radsupportmarks1_zpsa7e3ba2d.jpg.html)


Passenger side is allot more involved than I have seen on other cars and I have no idea what any of them relate to (wish I did) but really in the big picture not that important at this point

(http://i44.photobucket.com/albums/f49/firetrainer/Boss%20details/9F02G188388/9F02G188388radsupportmarks6_zpsc959d653.jpg) (http://s44.photobucket.com/user/firetrainer/media/Boss%20details/9F02G188388/9F02G188388radsupportmarks6_zpsc959d653.jpg.html)


I traced over again with paint - this time in two different colors just to identify different letters and markings. Worked much better than all one color

(http://i44.photobucket.com/albums/f49/firetrainer/Boss%20details/9F02G188388/9F02G188388radsupportmarks6highlight_zps58487d3a.jpg) (http://s44.photobucket.com/user/firetrainer/media/Boss%20details/9F02G188388/9F02G188388radsupportmarks6highlight_zps58487d3a.jpg.html)


Found the second rotation number  (would match the upper left corner on the buildsheet - and elsewhere, if I had one :( where I expected on the front cross member - unfortunately only one digit. Will have to search the interior for the rest of the numbers (001-999 was typical for most plants, most years during 64-70)

Engine compartment black is on so time for reassembly

Did try out something new, I reapplied the writing found on the radiator support with crayon again. Since I'm using newer paint with hardener its present look is more of day one - rather than maybe day 90 but we'll see what happens. Surely a different effect than under single stage original paint

Did shot a test panel to play with - might try tracing the letters with a brush and acid to see if I can get the crayon to break through and what ever takes place next

Was under the car the other day cleaning and thought I would take some shots while cleaning before the new exhaust from Scott Fuller gets here

Forward floor area
with Sound deadener application. Still don't understand why they would add the weight to a Boss with standard interior. Not the only one I've seen  ???

Oh that is how it is/was. The worker got a little closer to the center and the driveline tunnel on the one side. Notice the cool shadow left from the front seat belt anchor. Something you only get with a single pass a an applicator wand. Likely will not see that on a restored car :(

That's the plan - of course anyone thinking of using information and details from this example should make sure their car is from the same plant, time and options and reference other examples to secure reasoning and documentation for making choices for their restoration

Since the subject of strut rod bushings came up in another thread and I uploaded a bunch of pictures of the originals I removed from this car I thought it would best serve the members that they get posted here so that others using the search feature could find them here

Face of front strut rod washer and bushing. Seen a few rattle can passes of black paint over its short 30K miles  :( But it did protect the finish under the black. You can still make out the blue (often found teal also) peeking out through a chip or two int he black

Back side of the bushing assembly - more black rattle can

After the lip of the inner steel liner was removed with a careful application of a small grinder and some hand tools the assembly (minus front bushing) reassembled to show the order and direction of each bushing as found on car.

Both longer and shorter inner steel liners together

Just the shorter liner. Notice the small amount of markings on the lip of the liner at the bottom

Front and rear washers (painted is the forward washer) Front washer shows a "flying" F in a circle

Some pictures of the original ball joint rivets found on this example. Believe current (in the pictures tone/color of the rivet has changed over the years and through the cleaning process)

Jeff as nice as that undercarriage is I would just clean it as you would have a hard time finding one that nice here in the NE anyway. Your n-case snubber bracket is the early type not the 69 bottom trimmed back type did it get changed somehow or a factory mistake?  Also I see those bell spacers used on the back-up light stud nuts in your pic & I never see them used on 69-70dearborn cars but have found them on SJ cars?

Yes its nice though I do have a little overspray from the repaints I've sort fo just left it alone considering my current use for the car. Its nice to have even bare surfaces of the undercarriage where the jets of paint didn't get to still unrusted. Mostly on frame rail sides and corners. The factory galvanizing of these panels sure ahve done their job

No likely I just grabbed one from the pile 25 plus years ago when I put the car together. When I got it much had been taken off the car and stored in shipping containers with a ton of parts from other cars. So when it came time to buy the car (you know the game) it was grab this and that without always taking the time to make sure everything date was correct. Was in a rush given how the sale took place, the location and such. So grabbed a top loader from the pile of 20 or so. Grab an N case ...........

Will change the bracket to the correct one now that I need to change out the gears for the original 3.91's that I need with the original type of trans I installed when I put the original engine back in this time.  We've come a long way since the early 90's and before


Also I see those bell spacers used on the back-up light stud nuts in your pic & I never see them used on 69-70dearborn cars but have found them on SJ cars?

Goo eye and thanks for bring that up and making others aware of that Likely just like the bracket above - grabbed what was handy and for me that would have been San Jose stuff so will change that back out when I get a chance  ::)

two questions.

Its still has ORIGINAL Brake Lines!!???

I would not even know where to start on this restoration, (other than a lot of research) BUT how do you restore some of this?  Like the rubber suspension pieces?  On  a standard mustang you would just buy replacement parts.  For a BOSS I would assume you would need NOS?  At 47 years old even NOS rubber has got to be bad.  So how do you restore those areas?

Believe all but maybe one of my cars still have their original front and rear brake lines (think the Boss's rear is original but likely from my CJ I had)

I would not even know where to start on this restoration, (other than a lot of research) BUT how do you restore some of this?  Like the rubber suspension pieces?

Just inspect to see if they are usable, clean and freshen up the metal area, treat with your favorite dressings and put back on if it fits your planned usage for the car. If you can't you look for other examples, get someone to reproduce (or look into doing them yourself) or live with the best you can find until something better comes along


  On  a standard mustang you would just buy replacement parts.  For a BOSS I would assume you would need NOS?  At 47 years old even NOS rubber has got to be bad.  So how do you restore those areas?

No NOS is rarely the perfect answer since allot of "NOS" versions (in this case the flex lines) are the double crimped, markings differ and dates will likely not match. Believe currently these "later" versions are being reproduced

Engine compartment black is on so time for reassembly



Did try out something new, I reapplied the writing found on the radiator support with crayon again. Since I'm using newer paint with hardener its present look is more of day one - rather than maybe day 90 but we'll see what happens. Surely a different effect than under single stage original paint

Did shot a test panel to play with - might try tracing the letters with a brush and acid to see if I can get the crayon to break through and what ever takes place next




If the wax numbers are supposed to come through the paint, could you bush over them with grease or vaseline to keep the paint off?

Depends on if your looking for the ten year old look or as delivered I would guess. Don't recall every seeing day one pictures where the marks are visible. Currently (after a couple years sitting around. The texture of the marks and a few pencil tip sized edges of the crayon is visible. Pretty happy with the experiment and will likely reused the practice on real restorations. So dislike (besides it not being original looking) the marks that should be under paint applied to other wise nicely done cars

Just me ;)

Jeff,
This is a really nice thread with a ton of information. I have been going over my partially restored 1969 BOSS 302 in an effort to remove the 6 or 7 (I used to think it was 5 or 6) reproduction parts I had used in the restoration prior to stopping to concentrate on the 1970 BOSS 302. So currently I'm spending some time underneath the car looking at what is there.

John

Thanks John - surprising how much original stuff was still on the car after all these years (well until I bought it and put it away)  The low mileage helped allot - you know how hard it is to find a low mileage car is here in Calif.  But our 100K mile plus cars often look like other regions low mile cars.

Sorry I missed the opportunity to say hi at the open house. When they wrapped things up didn't see you - :(

We had left for Barrett Jackson, and there were quite a few people I missed. Name tags, a future must do. Yes my fairly low mileage Dearborn, July 10, 1969 built bought in New Mexico car had a lot of good parts as well.

My passenger side spindle is a D0ZA-3107- (blank), and the driver side is a D0ZA-3108-B.

You left out the most important thing about the engineering number . For those reading the suffix is the most important aspect of that engineering number . "B" = Boss . "C" =equals regular Mustang and Torino . One is rare "B" and one is common "C" . There is about 1000.00 or more difference between the two in today's market, that is if you can even find some for sale.

Remind me of when your car was completed if you could. Kind of expected to find some oddities since mine is such an early car. Of course not something I really even thought about 25 plus years ago when I found it in Hemmings sitting in the northeastern corner of the state. Another one of those adventures in chasing cars during that period

Bob,
Actually it took me longer than I thought it would to get back to editing the original post. So when I climbed underneath the car to verify the suffix the passenger side was blank after the D0ZA-3107-, and the driver side is D0ZA-3108-B.

Jeff,
From the stranger than what the heck department. The BOSS 302 I Pm'd you about with the C8OA-3107-C spindle on the passenger side. I took inside and outside micrometers with me today to investigate the spindles left and right. The C8OA-3107-C spindle on this car was identical in all respects to the KKXX spindle on the driver's side of the car. The C8OA-3107-C spindle also has the hardness test mark on it as well. I do have pictures. I'll post sometime tomorrow.
