I've got the 67 Fisher body manual. I did a quick flip through and didn't see any firebird specific stuff. Section 17 "Exterior moldings" lists Chevy A,B,F,X,Z bodies but Pontiac is only A and B bodies. So at least the seller is being straight with you. But I would assume most things you need out of the fisher body manual would be the same for Camaro and Firebird anyway. I got it for convertible top info, which is pretty good. I'd recommend it.
