i have a 78 firebird formula and i already want to put new fenders on it and a guy wants to sell me some fiberglass fenders for a 70s model camaro if i get these will they fit on my car? i know i cant use the same front nose but if i get a front nose piece from an old camaro would it fit onto my firebird making it a camaro? Would i have to get new doors for the fenders to fit? What else would i have to replace? I would get a new hood of course because im putting a chevy 396 into it and the old hood has no clearance.
