69 Boss 429 fender bolts
« on: December 31, 2017, 05:45:43 PM »
I am also trying to pin down the correct bolts if possible. Not sure if you want it attached to the current discussion  or not.  Move this if needed. Car is a 69 B9 9F02Z164### built 2-28-69. Any input appreciated.

Perfect place to ask

Look through my small collection of pictures for these cars and could not find a direct match and or great pictures to provide a definitive answer

Unfortunately I don't have real production dates on many of the 69 Boss 429 and of course many have been played with or restored at some point

What I can offer is the following. Hope it helps in some small way

Best I can do with the grainy pictures of two cars close to yours is that the pictures IMHO suggest that the flat headed RSC bolts were not used on either of these examples and more likely used the same as what was being installed at Dearborn on non-Boss 429 cars during the same period.

Notice the shadow produced by the raised lip of the bolt head in these examples

Mr Speegle you should get some type of medal for the time spent helping document and restore these cars. Will go with regular production bolts. Thanks, and have a great year.

I have a January 30, 1969 assembled Boss 9 Z150XXX that has two types of fender bolts.
     -the two verticle by headlights are sunken head Flag Bolts
     -eight of the top fender bolts are also sunken head Flag Bolts (these are the same that were on my May 15, 1969 Assembled Boss 9)
     -there were four unique flat bolts on the fenders (two on each side very first and last on the fenders)

Hope this helps.

Have a mix of fender bolts on cars made just before the OP's car also (in the 9F15xxxx range)  which include the three letter flat style also.  Those appear to have found there way into the regular 69 production  at Dearborn at different times during the production year. Have them on fenders and spring cover locations

Those look like the RSC bolts. Interesting they are on the ends of the fenders only. For now going with the flag style bolts unless future information indicates they aren't correct. What I can see of your car looks impressive.

just  for some more info, the bolts were yellow cad 2- I know a lot of you are going to say they were silver- 100% incorrect as I have had 3 original Mustang never molested and 1 was a11K mile Boss 429,
When I took the bolts off the underside were a yellow cad and talking to my platers they were yellow cad and the heat, sunlight, ozone over time took off the yellow cad.

I also over the last 30 years plus and going to the junkyard here in Calif as when I was removing these bolts off hundreds of Mustangs they were about 90% had yellow cad on the underside of bolts.
