Hello! A friend just picked up a 70 3/4ton 4x4 pickup with front drum brakes. I believe any axle from 71-87 will bolt in place of his current axle. Is that correct? I believe he will also need a new master cylinder to match. Will a 71+ master cylinder bolt up and work fine? And can he do the same with the front brake lines? Thank you!
