Welcome. A bit of caution entering the Firebird world, especially when shopping for parts. There are many vendors who through sheer ignorance (or worse) peddle a lot of Camaro parts as fitting the Firebird. Especially those companies that have a parts line for both.
Thus the reason why my first choice for parts is Ames Performance Engineering. Pontiac parts only. The others I use for "backup" are Classic Industires and Eckler's.
