...and they probably differ a bit from one kit to another. So now you're locked into buying two of the same kit to get four wheels.
The funny cars had them, but you ain't buying two of those to part out. The AMX is a tough piece, the Corvette even tougher. The "easiest" one would be the Popcorn Wagon (Chuck Wagon used the same chassis). Popcorn Wagon was reissued in the Nineties but that's nearly thirty years ago (!).
Seventies Corvette annuals had Hurst mags (which were discontinued in 1969, and were only sold in 14" X 6" (Vettes used 15" wheels). AMX kits only had stock wheels. None of the Econoline/Club Wagon kits had Cragars that I can recall. Another one to look at might be the Barris Ricksha, I don't remember what it has, but it has been reissued by Round 2.
