This setup is on my 64 f100 I'm thinking its a G-Body front clip.... I'm having to put some adapters on to get the wheel clearance... I have tried to cross the numbers on the rotors and come up empty
GM mid size cars, 79 - 80's Buick Regal, Chevrolet Monte Carlo and others. Some came as floating rotors and some were complete 1 piece hub and rotor.
