The rag joint was VERY close before..but after it would scrape the header. So we're talking less that 1/4 inch movement tops.
My body mounts are all solid Global West units. They all look the same and the floor around them looks and feels okay.
Yes I weigh in at around 220lbs, but I just cant buy that the car has settled so much as to make the rear sit an inch lower on one side. I'm not that fat Greg !!!

Its quite easily visually noticeable in the back...an inch difference is pretty big. I think I would have noticed.
The subframe alignment holes are still lined up. My car also has welded in subframe connectors, that attach to a 6 point cage. I would think that a control arm would give before the frame twisted....
So this AM, I jack up that back of the car, and put jackstands under the rear axle tubes, so the car is resting on the rear suspension...... the front in still on jackstands right at the body mounts by the firewall, front suspension hanging.
Everything matches side to side within 1/4 inch......
My next plan is to place the jackstands near the front frame mounts and let the front suspension hang and see what happens. Measure every point on the frame and car I can think of and then drop the car on all 4 again. If that doesnt work, I'll pull the springs....not a hard job, but just kinda a PITA.
