I haven't found a source that defines
ALL bolt sizes based on GM part numbers. I have found
SOME sites that list
SOME bolts, but not all. It takes some detective work and some trial and error.
Unfortunately, the fastener part numbers listed in "Standard Parts" (group 8.899+) in the Master Parts Catalog usually don't match the numbers in the Factory Assembly Manual. Some do / some don't. But it's a good place to start.

If you can't determine the correct fastener size, then post a question - go with the answer that you feel is best.
