I think those NOS Keystones are bitchin'! They may be a GM bolt pattern but I've always associated Keystones with being at home on Chrysler products for some reason. In fact, I can remember being at the Street Machine Nationals back in the '80's (the CC Nats!) and a friend and I made a point to count how many Mopars we could find with Keystones and the number was astounding!
