There is a vehicle up on blocks in my neighborhood and I'd like to approach on buying it but I'm not sure exactly what it is.......The vehicle grill is a 1971 and it is a convertible. The vehicle does have the double bubble hood which I have read was a 1970 Item not a 1971. The vehicle has drums on the front. If it is actually a GT, how many of the 1971 GT's were convertibles? Could it be possible a GT had drums?
