All of the Ford trucks from the mid 1960's through current production have used driver side drop front differentials. Doesn't matter if it is 1/2 ton or 1 ton, Dana 44 or 60, Bronco or pickup The 66-77 Bronco has a narrower track width than the full size models. Im excited to finally have this model of Bronco. I'll take the tires any day. They look very similar to the bias ply mud grips that were common on Jeeps, Scouts, and Broncos of this vintage. Thank you Revell.
