Those bolts may be the same size as the fender bolts. Some of the vendors sell clutch head bolts. link [oldchevytrucks.com] Just a thought. You'd have to bury them for a while to get the patina to match, though.

I believe those interior sheet metal screws are 8-32 (certainly not a fender bolt). The vendors sell new ones but they won't have the patina you want. If your original screws can't be reused send me a private message; I think I have a few used ones with patina stashed somewhere. Kent
Well either my truck didnt come with clutch head or mine were replaced with newer ones, because the only ones i found were in the floor pan. granted, mines a 55.2, so im not shocked either way. sorry i couldnt help.
