UCA adjustment plates damaged.

I worked in a alignment shop the specialized in all chassis work back in the 70's and probably did 1000's of alignments, class A motor-homes, set up race cars to have 0 bumpsteer, the old fords and Lincolns the frames would sag and you couldn't get camber so we would chain down both frame rails to the rack and jack it up in the middle with a 50 ton bottle jack to bend the frame rails back out. I aligned the mopars with the weight on the wheels, just jacked it up on the k-member so I could get over the tire and as soon as I loosen the cam nut the weight pushes it in, so when the cam gets turned it pushes on the inner tab to move the control arm out, for me I never really use the outer tab to move the control arm, the weight does that.
