My son in law has a '73 Barracuda, (now a 440 Cuda) which was a factory original 318 2bl single exhaust, AT car w/ slapstick, rally dash, console, power bulge hood, 3.23 single traction rear, all verifyable by fender tag, No Cuda badges anywhere. I dont know how many were original, but I have seen many otherwise plain round tail light Barracudas w/ Rally (Bulge) hood. I know the hood was an orderable by code item for at least '73 & '74, w/ no performance items required to get it. Ovmf
