All I did to the first one is tow it around.
The TJ is sort of a special case. The Previous Owner did some booty fab things like removing all the lower suspension mounts at the frame, then booger welding some back on in undesirable locations. He also removed the stock 4.0 motor, sold the hard top, doors, hood and front fenders. Last year I helped him swap a 2.5 w/ auto back into it.
I will be swapping a Waggy centered rear D44 (which came with the purchase) into the back and another Waggy 44 up front. Then I'll build some tube fenders and get it registered with 35" rubber.
