The GM "Parts Catalog" and the GM "Standard Parts Catalog" are two different items.... I have both. When I operated my own automotive machine shop in NJ, I bought so many Corvette parts that the Chevy dealer got sick of looking them up for me. They gave me a set of catalogs. Try punching in some of the AIM numbers at GMPartsDirect.com. One of your above numbers came up for me, the other (423582) did not. GM part numbers get superceded, sometimes many times, so the old AIM numbers are usually out of date. Shoot me an email with some fastener numbers and I'll dig the cats out of the boxes. Paragon & Doc Rebuild are also good sources. I use them regularly. I also have a 70 with a complete functioning wiper door.

Mike.... you have mail. Paragon & Doc Rebuild have a few of the pieces, but I could not locate the rod #3922390 so I took my car apart and sent you dimensions (& pics). You can (maybe) make one from the info I sent you.

Quote: Not sure if this is what you're looking for, but Paragon Reproductions has a chart that lists all the bolts. I think it lists 'where used' under each one, but ask just to be sure if you order it.:

That chart is great. It lists the major bolts/screws!

Another good source is a Van Steel Catalog, A Paragon catalog, and A VBP catalog. The 63-82 parts list thsat GM uses also has a breakdown whivh shows almost every part in the car also.

Quote: Yes, it is called the parts book.
GM dealers used them in the parts department and they can be purchased from time to time on e-bay.
When I restored my 68, I would find the part number in the AIM and then look up the part number in the parts book whihc very often as aprt of the description would indicate the size such as 1/4 20 1 inch long.
Very helpful.
Parts book also has nice exploded drawings of parts and how they go together, very worthwhile investment.
