I guess this where cheby got the idea to crab walk!

I fixed an old CJ like that, frt spring hangers weren't welded even side to side, took Me 5 tries to even get it all the way on the alignment machine w/o the back wheels running half of the rack. By the rear shackle angle, I knew I had to move the Dr. side back, almost 3/4" before it was right enough to align. Luckily, it had enough meat & was thick material, I did & then tack-welded the washers in place when I was done. Lined up like a pup, no more crabby GP, cool little thing w/a V6.
