Need Help Locating Part
I just got my rear bumpers back for the platers and plan to install this weekend. I was looking in the assembly manual and it shows a bushing (part # 6263571) placed in the hole were the bolt passes through the body. Needless to say I don't have the bushing and can't find where any of the major parts suppliers have it. It appears that this bushing may prevent cracking the body in some way when the bumper is bolted up. Is this part necessary?

The rubber cushions that Rebuild sells he calls "paint savers". These are placed between the bumper and the fiberglass body panel. These work the same as the body gaskets placed under door handles, taillamps, outside mirrors, etc. and were never used by Chevrolet. The bushing you refer to appears to have been placed over the bolt thread to provide a space between the bumper and the bracket, where the bolt goes through the rear panel. Having said that, I can't remember ever seeing them in any original cars I've worked on.

This may have been unique to 73. I don't have an open 73 AIM in the store, but a quick look at the 70 assembly manual shows no such bushing. My 1972 Corvette Factory Parts Book does not list it either. The illustration in the 72 parts book (and later parts books I have) shows the bumper flush against the fiberglass with a bolt, lock washer, and flat washer as the only hardware associated with mounting the bumpers.
Sorry I couldn't be more help. You might want to see if you could find sometihing that would work at a hardware store, or try to fabricate something. Good luck!
