Yeah AJ, i did some digging on the net and found out the front rotors of a 67 mustang fit 70 to72 cars with kelsey hayes 4 piston calipers, same bearings and all i couldn't believe it.... just wanted to know if i had to shim anything up to center the caliper if the depth had a difference in it. so I'm gonna buy some cheap rotors at autozone and figure it out..... love the fact that it carries the larger 4.5 bolt pattern, plus saves me a ton of work and my car gets to stay original..... best news I've seen all day :thumbsup:
