sbp disks

UCA and ball joints are the same on the 72 and earlier. I have not seen any "new" SBP disc brake set ups. If you go to salvage, be sure to get the proportioning valve and master cylinder, too.

The disk brake road wheels are different from the drum brake ones. The disk brake wheel had a ring on the back side which held the wheel flat against the "hat". I've used drum brake SBP wheels on disk brakes without an issue. I've made sure the wheel is squared on the hub and that the torque on the bolts is equal. I also did not do any serious canyon carving with it either.
