I built a 4 bar system similar to Kelderman's, semi rear track bars as has already been stated, got 5th bar, cut in half, put 1" rod in the. Middle, bent to match diff., for track bar. Track bars were about $40. Ea, quite reasonable. Ends are .875" ID, got moly impregnated nylon to bush down to .750" easier to get .750" bolts. Used 2 bags off a semi 4 bag system. This for 1.5 ton capacity truck. 4-53T, RTO, Brownie, D-80.
