Fitment & Compatibility
Select this rear conversion by the GM G-Body housing flange and measured 2.62-inch axle offset. Installation requires substantial housing-flange material removal and drilling two holes as shown in DS-1571; a qualified machine shop is recommended. Parking-brake cables and their connection hardware are separate. Check shock-mount interference, axle registration and clearance around the 14-inch rotors and calipers.
