Probably weren't any 14x7 rally wheels available yet, (which is why you can't find any dated that early) so any SS cars that had rally wheels ordered instead got silver painted 14x7 XT's with dog dish caps and trim rings...which was the closest the factory could provide for a 'rally" type wheel treatment without actually having the 14x7 rally wheels available, and to keep production moving. The dealer knew the guy wanted rallys and added the derby tops to the dog dish caps before delivery hoping the buyer wouldn't notice they weren't the rally wheels he ordered.

I believe the silver wheels, trim rings, and dog dish caps all are original to this blue car, nothing was stolen, and no "Cortez Silver SS car with XT wheels" was part of the mix...but there is no way they screwed those derby tops to the hubcaps on the assembly line. You're kidding yourself if you think they had someone at the factory taking rally wheel center cap parts and screwing them to dog dish hubcaps. That was done at the dealership. That's also why no other cars with this setup have ever been found, photographed, or heard about.
