disc brake set up

When I converted a slant six Barracuda to K-H discs in 2016, I could buy new Cardone calipers at O'Reillys, and new rotors from PowerStop.
Most of the parts I ordered from Dr Diff were drop-shipped from RockAuto. The brake parts anyway. I think the spindle might be exclusive to him, and the UCAs were reproduction, I don't think RockAuto stocks those.
