You would use the complete different brake system excluding the LCA. It will fit and bolt up if you want big bolt pattern. If you have a sway bar the calipers hwve to be moved to the rear with the bleeders on the top.

There is a difference. The early disk brakes where a 4 piston caliper small bolt pattern on the wheels.

The later 73 and later disk is a single piston caliper large bolt pattern on the wheels.

The later 73+ is a popular upgrade as it gives the big bolt pattern for wheels. In addition the ball joints and just about every other part is also cheaper for the 73 and later A body cars.

To do the swap you would need upper a arms with ball joints, spindles, lower ball joints, rotors, calipers, brake pads, and probably new brake lines.

I have the setup so I would move the calipers to the rear? So basically I would have to switch the spindles around to the opposite sides?

Zhandfull I think you misunderstoof I bought the 74 scamp stuff for the 67. I have the single calipers piston ucas lcas ball joints everything even the prop valve.
