Okay, I see the problem now. Those are original Magnum 500s. All I've seen are the reproductions. They're quite different. As expensive as the new ones are, I imagine the originals (if available at all) would be more than the car.
i remember seeing 71-73 cougar having them wheels. I had a set a while back that were NOS (still had the ford tags on them w/ a wire loop going thru the stud holes). So as far as the 70 goes i dont think the 70 cars had them 71 n up did i believe
Painted Magnums were 14x6" on Mavericks and Granadas. The bigger 76-79 Torino, Ranchero, T-Bird and Cougar were available with the 14x7s. My BetaCat is wearing 14x6s from a Granada/Mavarick, and I mounted 215/70/14s on em. I bought a set of 14x7s down at SuperSwap years ago for AlphaCat and mounted a set of G-60-14s (new size of 245/60/14), but now I'm not gonna use them for that.
I haven't decided which set I'll be getting rid of. The 14x7s were just reconditioned when I bought them, and the 14x6s were take-offs from a car in a junkyard.
Be advised that the trim rings for the two are different. The 14x6s are narrower than the rings on the 14x7s.
