In answer to this thread, I prefer Cragar S/Ss, but I remember almost all of the Drag Race Mopars running Keystone Klassics back in the 60s and 70s. I had a set of Cragar S/Ss on my '64 Pontiac LeMans Convertible. I bought the wheels in 1975 and they were Uni-Lug, 5 on 4-1/2, 4-3/4 or 5 inch lug stud spacing. I had 8" wide wheels on the rear with L60 Posi-Trac Torque Twisters and 6" wide on the front with 5.60 tires. At that time, the Cragars were less expensive than the American 200Ss or Torque Thrusts, which were my other preferences. I also preferred their steel rims because, at that time, we did not have good enough adhesives for stick-on wheel weights to stay attached to the rim. I did learn how razor sharp the chrome plating on the Cragars was when I sliced my thumb open while polishing them one day (anyone remember Mother's Mag Brite?)
