I found a 1970 1/2 ton 4wd for sale. But I really wanted a 3/4 ton. I was wondering if a 3/4 ton lift would bolt right up and stiffen my suspension. Also I have a 1980 3/4 ton that I could steal the axles from. Will they bolt up to the 1970 without any serious modifications to steering or anything. I may not need the 3/4 ton axles I dont know. I plan on lifting 4 inches and running 33's. Not much wheeling just a little mud. I would appreciate any thoughts.
