Title: 1971 429 Alternator Splash Shield
Post by: sah62 on April 25, 2013, 05:53:55 PM
Ed Meyer recently asked me about the possibility of reproducing the rubber splash shield used on 1971 429 Mustangs and Cougars. I did a little research and found a template on the 71 429 Mustang/Cougar Megasite:

I've attached a copy of the 10317 section from the final edition of the 1965 - 1972 MPC. I have some questions before I dive into this project too deeply:

Can't be of any assistance - never found one on a car yet.  Would share that my fairly early Cougar that should have one does not have the mounting holes for it for some reason. Just mentioning since this might be something added during the year.

Good luck with the project

In examining your attachment it indicates 72 All V8's.  In review of the megasite I believed this to be a 71 429 piece only.  Is anyone aware of 72 applications of this piece??  I will reach out to some folks I know with 429's to see what feedback they may have on the part.

The 1972 info is for car line "S", or Thunderbirds. It's a different part.

Any luck? This is a very doable project for me, but I need to get the thickness right.

Still awaiting response.  Let me email them again.  Sorry.

I heard back from one of my 429 contacts and he has never had one of the splash shields in his posession.  He too has only seen pictures.  Still awaiting response from another person.

The engineering number for the D1OZ-10317-A is D10B-10317-AA.  I cant say what the difference is but with the different part numbers and different engineering numbers there is a difference for sure.  And keep in mind that a D1OZ was originally a Torino part or designed for a Torino but used on a Mustang for some reason.

I have access to a low mileage original 429 convertible and can look at that this week to see if the shield is still there and take measurements if needed.

Yes, please, Marcus. Where did you find that engineering number?
Title: Re: 1971 429 Alternator Splash Shield
Post by: J_Speegle on May 02, 2013, 07:48:09 PM
IF not next best guess of thickness might have to come from a similar pieces on another Ford line

I will go and look at the car on this upcoming Monday or Tuesday.  Owner is out of town till then and then I can see if this piece is still on the car.

I also agree with what Jeff says here that there is probably plenty of other pieces on the cars of this period that used the same material...so one way or another should be able to figure it out.  I can always take a walk over to Desert Valley Auto and look thru there as well.

I know of at least two different parts (the 67-70 Mustang rear lamp shield and the front bumper/stone guard shield used on 1969/70 Shelbys) that use the same material, but the thickness is different. Finding an original part will make it a lot easier to produce an accurate reproduction.

What about early mustang under fender splash shields stapled to metal mounting plate how thick is that rubber shield?

In many examples that is more similar to the hose straps used for PS or heater hoses in the engine compartment - and not always a consistent thickness.

Scott yes your two examples are different thicknesses but they were designed and produced likely by different suppliers and for different purposes. If we could find a alternator splash shield on a early 70 Merc, Lincoln or T Bird  might be closer. Just a thought

I took a look at the 71 I have here close by my shop....its built in October 70 and no signs of the shield, if it was ever there.  Car has been sitting since the 1980's so its not impossible that it came off a long time ago.  No luck here....

Being an early car it might not have had one - My December one (as mentioned) didn't have the mounting holes for it.

The engineering number for the D1OZ-10317-A is D10B-10317-AA.

Where did you find that engineering number, Marcus?

A useful source has been able to provide me with original engineering drawings for both the D10B-10317-AA and D1ZB-10317-AA shields. They are indeed very different, but at least both drawings describe the thickness as 0.075". I can get 0.080" material, which is close enough to be indistinguishable.

Scott,  Its from a Master Cross Reference List....do you not have one of these?
Title: Re: 1971 429 Alternator Splash Shield
Post by: sah62 on May 10, 2013, 07:53:56 PM
I have several, and as I noted in the original post I don't see it listed in any of the them. Which one (which date?) were you looking at?
Title: Re: 1971 429 Alternator Splash Shield
Post by: Anghelrestorations on May 10, 2013, 09:20:29 PM
Scott, I dont know at this point exactly which one it was since I have a stack of them, but at this point means I have to go thru all the books all over again.  If you dont think the number is correct let me know why, but otherwise I dont see the point in going thru the whole exercise again.  Dont take it the wrong way, just trying to be realistic here.

Marcus, I'm only asking because I'm thinking about making a $1,000 investment in reproducing a part and I'd really like to be sure that the details are correct by confirming them myself. The D1OZ-10317-A/D1OB-10317-AA numbers aren't  listed in any of these cross-reference manuals:

Volume 4, October 1971
Volume 4, October 1972
Volume 4, April 1975
Volume 5, October 1975
Volume 5, April 1976

If I can't confirm the numbers and applications I'm not going to reproduce the part.

Well, if you put it that way then I guess I better help....

You need Volume 3, April 1971 so you can see this.

No problem.  So now you HAVE to make these.....and I guess I will need to look at buying a 71 so I can put it on there.

This is what the D1OB-10317-AA shield allegedly looks like. Has anyone seen one like this?

Hmm very different look than what is posted over on the 429CJ site
Title: Re: 1971 429 Alternator Splash Shield
Post by: sah62 on May 20, 2013, 08:15:55 PM
Yes, but they're two different parts, Jeff. From what I can figure out the drawings posted on the 429 megasite describes the later D1ZB-10317-AA shield.
