The guy that posted on pirate 4x4 is on the right track, I have narrowed rear ends and the set up I used was 2" and 2 1/4" solid round bar through the middle, believe it or not when you weld the tubes, TIG or MIG it still pulls and bends that 2" solid bar, but if you heat and cool the tubes until the bar slides out nicley then you know it is straight.
