My '72 Challenger lid has all of the holes for a T/A spoiler and go-wing, as well as the light and rack. But, that's not all that surprising since it was probably going down the assembly line at the same time as Super Blue's, as it has the same 8/17/71 build date.
As Super Blue already knows, my car also has '71 style door glass and a '71 style fuel tank (with the vapor tube) as well. My car isn't exactly a survivor, so it may have had other '71 model years items when it rolled off the line.
