I thought if ever I would change my "K" to disc brakes, I'd use the factory system from a '68 'C' body. I have a complete set (spindles as well) from a Fury I haven't used. Main problem is once the rotors are worn out, not sure about finding replacements. I like my 11 x 3's, I probable won't bother to change over. You're welcome to take a look if you come through San Bernardino area on your way to Spring Fling. Also have an extra left side original (good/used) motor mount. Or if you have an extra right side, you can cut and re-weld the flange to make it work on left side.
