I've got a 1976 (originally 455) four speed Trans Am. Original 455 is long gone. Trying to make it a 1972 Trans Am clone/recreation. At least the front of the car. Already have an original 1972 endura bumper/ nose, grilles, lower steel valance, and headlight trim. Trying to verify what else is necessary to make this happen. Radiator support? Fenders? Correct bumper brackets??? Sorry to any purists but I love the look of the 1970-1973 Firebirds. They're getting very difficult to find or just way to expensive to buy one. Or people want a fortune for a rotting carcass of an incomplete rust bucket. Any help is welcome. Thank you.
