Disk brake parts swap

Knuckles and brakes, yes, control arms no. You need either the ball joint adapters from Dr Diff or some 73-76 style upper control arms.

You would also want to use 73-76 A-body lower ball joints.

I just did this swap and this is 100% correct. My dart is a 73 so I used the same control arms and used the spindles and brakes off a 1980 volare. I had a major head ache dealing with this but inspect the spindles closely! One of mine was bent so after it was done and went to an alignment I found out it couldn’t get better than -2 degrees camber. Had to pay for extra spindles and then have the shop swap them.
