1964-72 Chevrolet Pontiac Buick Oldsmobile A-Body F-Body X-Body Brake Rotor Dust Covers 2pc These are the factory correct style rotor spindle nut dust covers that go on the front rotors. They are for all factory rotors with the 1 3/4" hole. They are also used on the drum brake hub from 64-72 A-body and 67-69 F-body & 68-74 X-body. These were used on all mid size gm cars from 64-79. This is the factory correct design with the bump out to clear the end of the spindle. The replacement cover, that is still offered by gm, is a replacement and never came on the factory cars nor does it look like the original. These covers are always dented and beat up after being taken off the first time.
