They are different due to the rocker trim being different. There was a thread awhile back about this.
If Ames sells one only for Firebirds, I'd go with that. But it is possible Ames sells the same one as the others and just doesn't list the Camaro.
Maybe someone who has bought theirs from Ames can fill us in.
Overall in general, My PO is that Ames has the best stuff for 'birds, but their prices aren't always the best.
