So I'll probably be helping my dad convert a 1989 MJ from 2wd to 4wd. He bought 2 cars at an estate sale and with the sale of the focus basically got the MJ for free. He's in Florida so it's a 2wd but its at least got the 4.0 motor and manual transmission. We are looking at doing the swap at christmas when I'm down there to help him. I know most of the XJ parts will swap over. plans are for maybe a 3" lift and some 33's. I'm looking for advice on what years we should be looking at for the axles. We don't have access to a welder so bolt on axles are preferred. based on what he'll do the Dana 30 front and Dana 35 rear will be okay. He's going to use it for the usual home depot runs and hitting some trails in florida so running in the sand. Bumper recommendations are also welcome. Thanks in advance for any advice.
