I was going to say that the subframe bolts have quite a bit bigger diameter than the core support bolts.   Go try this - take one of your core support bolts and see if it screws into a body mount.  I'd bet it doesn't and that should answer the question whether your's came with all the same bolts.

Here's pictures of my original bolts.  These were taken before I had them re-plated.  They've since been replated (black phosphate) and look brand new.

Also, if you're looking for reproductions, AMK Products appears to carry them.

Reference page 30 for 3914816 for the Core Support Bolt:  http://www.amkproducts.com/Catalog_PDF/24-38.pdf
or here's a direct link to the part:  http://www.amkproducts.com/bulk3.asp?part=B%2D10079

And reference page 23 for 3912533 for the Body Mount Bolts:  http://www.amkproducts.com/Catalog_PDF/6-23.pdf

However, the head markings for the body mount bolts differ from what were factory installed on my Camaro which are R - B  - W not "A" as per the repo.  The "A" could be correct, but they were not used on my '69 Camaro assembled in Van Nuys.

Hope this helps.

According to the 1969 Camaro Assembly Manual, Page 41, the Core Support Bolt PN is 3914816 while the Subframe Bolt PN is 3912533.   As the PN are different, it's most likely the actual bolts are different.

I'll post pictures of mine in a little while.

I am pretty sure those are the core support bolts, not the subframe bolts.   Subframe bolts do not have the "built-in" washer.

I have pictures of both and will try to post later.
