This is a 3.23/posi 10-bolt disc brake rearend. This rearend is in excellent working condition and comes complete with rotors, iron calipers, e-brake cables, master cylinder, proportioning valve, and rear sway bar. Just about everything you need to convert to rear disc brakes is included. This piece has some typical surface rust but is in excellent working condition. The brakes seem to work fine but it may not be a bad idea to rebuild or replace the calipers. We would also recommend replacing the brake lines.
