Inquiring minds want to know. Got into a discussion today with someone who said all A body mopars that came with front disk brakes and 4'' bolt circle had 11'' rotors. I thought they were all 10'' rotors.
65-72 A body cars with the 4 inch bolt circle, Kelsey Hayes disc brakes, had a rotor diameter of 11" inches.
I would know, as i rebuild lots of these disc brake systems.
