If I was a diehard Firebird fan this would not set me back. If you got the money you could get "Firebird", since they are just copies of Camaros anyway.
Some aftermarket company should/needs to come out with a Pontiac style nose clip, spoiler and emblems, use the T/A picture above as reference, I bet they could sell the shit out of them.
And if all else fails, call Chip up and have him model something up for you
