Can't Stop 71 440 Demon

1974 A-body brakes work great. You will need the Large Balljoint upper control arms and the complete spindle ,Rotor ,Brake assembly. Very reliable and easy to maintain. You will have a larger 4.5 bolt pattern . Moser Eng. do sell rear axles with the 4.5 BP. I am referencing 1974 but it maybe 73-78 just not sure.
