body & running gear is all intercahngable from '61-71 same with 1/2ton & 3/4 ton running gear, the 1 ton frame is different and 1 ton running gear will not fit due to the different frame width. You should have no problem installing dana 60 rear and 44 front w/8 lug from any truck between 61-71.As well as cabs, beds, grills, etc. the only difference is the motor/bell hsg/trans mountings, from 61-68 it is a four point mtg (2 on engine, 2 on bell hsg) 69-71 has 3 point mtg..(2 on engine 1 on rear of trans) and the only other difference is 61-68 use a hydraulic clutch throw out and 69-71 use a mechanical clutch throw out.
