I just bought me another pick up it's a 1983 F-250 4x4 Reg. Cab. Long Bed, with a Gas 460 and a auto tranny. Body was in pretty bad shape but I bought it mainly for the 4WD system. Now would this truck have a Dana 60 in it or a Sterling 10.25? It's missing the I.D. Tag on the axle so I can't I.D. it that way.
