3/4 and 1 ton GMC's would have the rear axle under the rear leaf spring, the 1/2 ton would have the axle on top of the rear leaf spring. The 3/4 and 1 ton GMC rear frame is narrower than the 1/2 ton GMC. Over all frame would be longer on the 3/4 and 1 ton GMC's unless the 1/2 ton was ordered with a longer bed. Regardless the 3/4 and 1 ton GMC's frames are narrower than the 1/2 tons. 3/4 ton GMC's have 16" wheels in 1946, Chevy 15" in 1946, both 8 hole.
