Its transmission is a SM456. There are tons of 3 / 4 that the only manual I could get. You do not build 6 lug 3 / 4 ton is not in 81st is 81 / 82 about the time he began to walk with a bolt 14 semi floating rear. I am 14 Screw Company fully floating rear ends seen in 3 / 4 ton to 82 and half before 81st Floater screwed to the ends of the axes in the center of the rear axle? If required a full floating rear business. Call a business, because they are manufactured by GM by American Axle Manufacturing. Full floating is the weight of the car with the support of the tubes axes about axis wheel bearings inside and outside. the shaft is fastened by screws on the bearing seats. All the wheel axis is not driving. When half the weight of the vehicle floating in the shaft with a bearing of the wheel of a truck 1 / 2 Ton. The shaft is held in the vicinity of the internal gear with clips of CA as a truck 1 / 2 Ton. The full float rear is a lot better. Check with us if you wish.
