I aquired a 6" thick parts and illustrations manual from an old pontiac dealer. It covers all Firebirds, Formula's, and Trans Am's for the third generation (82-92). It has every part number known to man for every firebird car between 82-92. The book weighs in at 13 Ibs.

So if you need any GM part number for any reason for any firebird, let me know. I just got this book so I will have to learn how to use it cause it's almost 2,000 pages.

Please don't lock this cause it is third-gen tech related

 

Thats a cool find. NOt to sound too much like an ******* but i bet half of those parts have been discontinued. at least thats the way it is with my 87 IROC. good luck with the parts
