Not a clue to be honest. The first set of Magnum wheels we tried on a '73 Charger, thought they would fit, but ended up taking a BIG aluminum hogger on a die grinder with hours of grinding to make em fit. The '66 Coronet there we just threw up on a mill with the tire still on LOL. I think it has something to do with the center caps, but I'm not sure. And another set for a different coronet we had milled out. But the Chrysler 300c wheels just fit right on.
