I hope I can get a few ideas here, I want to build a daily driver 1/2 ton 4x4 that would be reliable, can get some halfway decent mileage and tow a car trailer once in a while. I have been mentally piecing together a truck and don't want to learn by trial and error. I have a 6 inch complete lift kit(brand new with 4 springs shocks drop arm etc that I got for $250) and a 700r4 transmission, and that is all. I want to start out by finding a donor rolling chassis and hopefully go with a new 350 from Jegs, the 700r4,I think I need some sort of a spacer and it will bolt to a 203 xfer case? what year axles will fit?71-72, 73-87 axles, are they all the same? they are a dime a dozen. I want to go with the 6" lift. I was thinking 33" tires and wondering if I should be looking for 342 gears? 308? 373? I figure I will worry about the body later since that will be the easy part. thanks for any help!!!!
