Pig tracks I guess I never paid much attention til I started working on the Challenger, My nephew gave them to me cause of some money he owed me. Not sure where I got the idea they were aftermarket. Buddy at work may want to trade me though!! He says he has some Keystone Klassics he's willing to swap. May just keep the Rallyes, however. They are a nice enough looking wheel. 'Specially if I get rid of those dang white walls LOL
