I'm wondering if anyone knows if the actual pontiac fbody frame changed from '82 to '92. If so, what years were different from the rest.

I'm pretty sure that '85 to '90 wer probably the same exact frame. But what about the other years.

And, for that matter, what about the difference between the camaro and pontiac frames?

Also, has anyone seen scoops like these (in pic) that are under the nose cone like that. If so, where do you get them?

 

our cars do not have frames they are unibodies.... they do have sub frames and i ams sure that they are all the same, but i am not 100% positive on that.

the scoops are probably custom made

 

The only differences that are worth mentioning, is:
82 & 83 had a different rear axel, not really sure how tho, it does fit on 84+ cars tho.

THe only differences in from Camaro to Firebird is basically cosmetic, other than a wonderbar for the IROC, and other bolt on items.
