You would need to change your "upper control arms to the "small ball joint" 1972 and earlier ones to use my brake set up on your car.
You already have a large ball joint, even though you have a slant 6 car.
And yes, you would also need a 65-72 A body DISC BRAKE lower ball joint.
Seems like your thinking this kind of swap out, but no matter which way you go, it does sorta, kinda, get expensive in the pocket book.
