Replacement tab for the weak factory D30 axle end upper control arm mount. 1/2" thick steel. Upper hole, 2.1" diameter, sized for aftermarket joints. Factory bushings are 1.75" in diameter and must be sleeved to fit(a short piece of 2"x.120" wall tubing works well). Bushings or joints must be welded in, NOT a press fit. Depending on brand, aftermarket joints may have to be offset to clear grease fittings(others use a drilled bolt). Includes main tab and two G120 gussets.
