Bolt source-plastic cover plate for lap belt

These are the hex bolts with the thin heads. They look like sheet metal bolts that bolt into the unthreaded holes in the underbody reinforcment plate for the lap belt retractors on a 73

Are you referring to the sheet metal screws, GM #9433253, that retain the belt retractor COVER? If so, those screws were never available from GM in SERVICE. I don't know that exact configuration reproductions of these screws are available. Frankly, unless they have a lot of other applications, I would doubt it.

If the above are what you're after, I'd call Pacific Corvette in Puyallup, WA. They dismantle Corvettes and inventory all parts by original part number. So, if you use the above number, they should be able to tell you right away if they have them.

I have found no sorce for thease screws and most of the time rust makes them break when removed so they are very hard to find. Under the seat I use fender washers and screws and hope to save a few originals to use where the judge can see them.

Thanks Joe and Lyle,
I tried very carefully to salvage these when I was taking it apart, but I never succeeded in salvaging any of them. It was hard to even get a grip on the head since it is such a low profile.

I've contacted Pacific, but I suspect that they don't even bother salvaging them.

Any idea of what the thread shape and size should be. They must be a thread forming screw since the underbody reinforcement is only a small hole.

It's a 5/16 hex head and about a #8 metal screw.

Joe,
These are the right screws. The AIM refers to this as a screw assy. Is it possible that the big 3/4"flat washer is actually pressed onto the screw? Is there info available for the subassy?

Thanks Lyle,
Do you know what the finish is, the length of the thread. It looks like the hex head is flat and not indented.

It's very possible this was a screw with a captive flat washer, as you describe. These were often used in PRODUCTION as an assembly convenience.
