I am looking to see if someone with either an original car or well documented, can tell me the bolts that are used on their fenders, Dearborn Dec 3 1969 time zone. Here a re six bolts I put together, not sure if any of these were used at that time period or not. Any input appreciated. Thanks!

Armond,
Off hand, yes. Fender bolts with those head markings look "appropriate". However, most of the Mustangs I see on the West coast are San Jose built. The underside of the washer should be smooth, no "teeth".

Yes thanks Jim, I am just trying to narrow it down closer to when this car was built, hoping someone has one close. It is for a Boss 9 I am restoring so I am being more neurotic about this one.
-
Armond will look through my picture collection focusing on the 0F140000 range and report back
-
Thanks Jeff!
-
One and five are typical. Armond, send me your shipping address I've got the panel boxed up.
-
Thanks Bob! Message sent to your email.

Hi,
My Dearborn Boss 302 0F119XXX, October 13, 1969 build date had bolt number five in most fender bolt locations, with a few large washered SEMS thrown in here and there. Hope this helps!

From the picture, types 1, 3, 5 and 6 are grade 5.1, types 2 and 4 are not. Conventional wisdom has indicated the grade 5.1 fender bolts were used by Ford from 1968 on.

Thanks for all the input! Just what I needed.

Bolt head design #1 (small flags) & #5 (circle L's) were were the ones I found were used in the 140000-150000 range in 1970 production at Dearborn
On my best example there was a mix on the fender attachment.

On the spring cover/shield attachment I found all #5's

And all appear to be Grade 5.1.

As specified, they should be cad plated. As cad plating is falling out of favor, try a dull zinc finish after bead blasting.
-
Thanks for the pictures and your time looking Jeff. It looks like I am going to go with #5. Thanks for all the help guys!

On one of the threads at the Boss site there was a discussion about B9's having different fender bolts than regular production. Reason was the fenders were removed at Kar Kraft and reinstalled. I paid attention to it because in my ignorance I tossed the original bolts out.
Link shows a RSC bolt. There are several threads on the subject. Sent E mails to AMK, they weren't interested in reproducing them. Potential sales would be too small.

The RSC bolts were also used for a short period on non- Boss 9 cars also but not during the period asked about
-
Armond, found this old subject on the RSC bolts. Apparently they are hard to find. Did you ever find a source for them?

Armond - see you asked a similar question over on the Boss site. Two different cars or did you forget to mention you were working on a Boss 9?
Just trying to get you the best answer(s)
-
Yes it is for a 70 Boss 429 I am restoring. The front end was worked on in the past and had a miss match of bolts. The car had been sitting since the mid 70's. I want to get, what would be consistent for this car. I had a 70 SCJ car sitting here I bought for a number of years and never took note of it before I sold it, built just about the same time. Pretty dumb! I was looking for a couple of the RCS bolts for my 69 dearborn R code that had them, I lost a couple of the hood large washer bolts. I took the car apart back in 91. I found them thanks to Scott at West Coast Classic Cougar. Thanks!

bgp429 where did u get the info in your post that the fenders were removed then reinstalled at KK on the b9s ? just curious
-
It was a discussion on the Boss 302 site. Went back there, did a quick look and couldn't find anything. It was a few years ago I heard it. May be start a new subject over there.
-
Workers there may have been supplied with fender hardware/bolts so that they didn't have to run and chance any that were dropped or lost during the re-installation of the fenders. Those may have been from one of the same suppliers Dearborn used but since they didn't go thru the volume of bolts the assembly plant did they may have only been one style there.
This possibility and/or just workers being human may have produced some of these patterns we see when they re-installed the fender bolts. Guys do some odd things at time to break up the boredom but they often do the same thing over and over so patterns emerge even from these
Just a possibility
-
the boss 429 fenders were installed & painted at the dearborn plant all BEFORE the b9s were shipped to KK & the only part painted at KK was larry l painting the fiberglass b9 hood scoops.

The only sites I visit are here and the Boss exchange. Could have assumed the fenders were removed based on the different RSC fender bolt discussion. No intent to mislead.

i got a big metal tray full of fender type bolts from a guy who worked at the KK plant & when i separated them in bags i ended up with 5 different head markings on that type of bolts. They werent building show cars back then & the y didnt bother to make sure all the bolt head marking matched.
-
They weren't building show cars back then & they didn't bother to make sure all the bolt head marking matched.
One of the most accurate statements made to date.

As we've discussed here many a time at the car assembly plants we've found the evidence where the transition or overlap of two providers of a specific bolt or hardware were mixed in the bin during transition much like the older food is added to the new batch of food at a buffet (for lack of a better description) creating a mix for a period of time. And I think we've worked to show, when they turn up, the mix of head markings when the data shows up.
Sure that many of us can recall the 80-90's when were often present on the show fields or at auctions with every fender bolt head aligned the exact same way, head markings all aligned with one another, all the valve stems on the wheels at 12 or 6 o'clock and all the hubcap horse level and facing the same direction - details such as that

Armond, For what it's worth, My 70 Dearborn Boss had all matching fender bolts when I bought the car in 1986. They were style number five. The build date was 12-1-1969 OFO2G1362??
-
Thank you for the info, this car was built Dec 3, two days later. So I have decided to go with #5. They are the majority of what was still on the car. Thanks!

think your going to have to find someone that has disassembled a car or has them sitting around in their hardware bin. Fairly typical for owners and builders in the US - just going to take someone with the time to look through a bunch to find them with the desired markings. Fully understand that in many other countries this is seen as a luxury. Just picked up a couple of coffee cans )for those who still remember those 8) full of nuts and bolts at a swap meet today, from a Mustang shop. But they all appear to be earlier stuff and likely mostly SJ focused

AMK does have them in the bulk kits. The longer 1 3/16" bolt is kit number B-11935 The shorter 1" kit is B-11547. These are 12 bolts per kit. I wanted to compare them to my originals I do have and the GL casting is lighter than most of what I have, but I do have a few that are just like AMK. So clearly they had slightly different stamping's. In the pic below you can see the difference in a few. AMK then an original marked (more) and another one with a slightly smaller GL marked (less). Not much to complain about. If you want to be anal about it,like I am, well here ya go.

ok thanks, i will order some.
