There is lots of welding and fabrication involved. You will need to fabricate all new suspension mounts, both frame end and axle end. Your stock short arms are not up to this task. You will probably need to build a fully customized suspension to handle the weight. Heavier duty arms, mounts, and good joints. Then you will need to build up a brakeing system. I am not so sure pinion brakes will get you past saftey inspection. I hear that people are doing disk brake setups with heavy ford disk parts. Then you will need new rims and tires to fit around the axle and keep the pumpkin off of the ground, and of course all new driveshafts. For a TJ this is pretty involved. I would buy an older jeep and start with that. You are basically going to be able to get a jeep and the axles for what you can sell the TJ for, and you cut off almost everything attached to the frame to do a swap like this. Chances are that with the larger tires you are going to want to stretch the wheelbase. You will also need to customize all the stearing. Then you just pay for the rest of the upgrades. Keep on searching, and there are people around that are more than willing to get dirty helping out. I think that Scarface is doing this swap right now on a tj. Looks like he striped everything and is starting from ground 0.
