Isn't that one the model with the bolt-in front crossmember? It would be simpler to just swap the whoe unit, crossmember, springs, control arms, and all. Maybe I'm thinking of a later model, but on some of them, it's possible to swap the entire front suspension with about 8 or 10 bolts. I don't think the control arms, bushings, etc., are the same from 1/2 to 3/4 ton.
