MM,
We think alike.
I'm a firm believer in 'period' wheels for a period car. If yours is 70 or earlier, Torq Thrusts Ds are availavle in 16,17 or even 18" these days. Good old Cragars S/Ss are still around but sizes are pretty limited to the more popular 14 and 15" sizes. Keystone Klassics? - My one bud had 'em on his 71 Mach and they looked perfect on there. Alpha Cat had the 14" polished aluminum slots. Beta Cat has 14" painted Magnums.
The big problem is finding a decent set of performance tires for our heavy Cats. About the biggest 14" around are BFG radial T/As in 245/60/14, which translates to a G-60-14. Not all that impressive. Moving up to fifteen inchers gives you a few more options, and many more performance tires are coming out in the larger 16, 17 and 18 sizes, but here again we run into what modern wheel would look 'right' on our thirty-plus year old Cats.
Quite the dilema, eh?
