I have tried online but have had no luck.

I need part numbers for things like rear tail light lenses and interior parts as well as engine parts.

Does anyone have a good website, or a good book?

 

Try Mike Metzler's 82-91 Camaro CD, which provides not only part #s but also diagrams. It's well worth the $25, IMP.

I've been meaning to pick up the 1982-1991 firebird parts and illustrations manual but I havent found a good one at a reasonable price yet. That would be the best source for part numbers short of the GM dealerships software. Calling a dealership and asking the parts guy would probably get you there. My cover story is that I'll need the part eventually and can save them time when i come in to order it... works like a charm, and for the most part its true.
