A buddy of mine has a dually for sale or parts. Its a 1981 1 ton 4x4. So wouldnt this have a dana 60 axle in the front and a 14 bolt rear? Would it be worth buying them both as a set for $600.00? I am not interested in weird dual wheels or offset front rims. What would it take to return them to normal style axles? Also, what gears came in the dually?
