Manual sbp front disc conversion feedback

The piratejack kit is just the later 73+ A-body disk set up. They take rotor blanks for the BBP 73+ disks and have them drilled 5x4", and turn down the center register on the hub. The center hub is still too large to be used with most of the original SBP drum wheels, but I think they work with the SBP disk wheels.

The rest of the kit is straight up 73+ parts. The spindles are the same, so you'll need ball joint adaptors if you keep your SBP UCA's as the spindles use the later large ball joints. That kit will also increase the front track width compared to the SBP brakes, so if you have wheels with a shallow backspace they may not fit with those brakes even with the SBP.

The brakes themselves work well, and on the upside if you ever do decide to go BBP later you can just buy a set of 73+ rotors, the rest of the stuff can stay the same.
