yes
There were no IROC Camaros in 1991
yes it should all be the same including wiring hookups from 82-92
5 x 4 3/4. Same as camaro, firebird all older chevys.
Yes, but 1991 rims will NOT fit a 1993 camaro
It is listed in the 1991 Pontiac Firebird Operations Manual
no it will not
I would think so. The 1982 to 1992 Camaro/Firebird are the same generation. There wasn't much that changed in the way of the body on the cars. They changed the front and rear bumbers/grills/lights around a little, but even these will swap from year to year in entirety.
Yes.
Yes
I calc'ed my '91 V8 Formula Firebird to be about 18 mpg.
A firebird can't "have" third gen. It either is or is not a third generation firebird, and Yes, a 1991 is a third generation.
If they are both Chevy V8 cars it will bolt up.
