The 3/4 used the HO52 5200lb capacity while the 1 ton used the HO72 7200lb capacity. The rear ends look very similar, but the HO 72 has larger bearings and lower gears. 2 or 3 piece rims were the heavy duty option on all models 1/2, 3/4 and 1 ton during this era ( rims were wider and could handle higher capacity tires of the era), however, one piece rims were standard equipment on all 1/2 3/4 and 1 tons. Both 3/4 and 1 tons use same 8 lug pattern.
