Problem: Here are the ride height measurements (from center of fender lip):
LF: 27” … RF: 26”
LR: 26 ½” … RR: 26”

Now, the car had the RH sag before I did this, but I hoped/thought the old springs were the primary culprit. No dice. I can live with the ½” difference in the back, but the difference in the front is noticeable. Plus the RF wheel has too much negative camber and I am out of adjustment room on the arm (guess I need the 5” adjuster sleeves). At this point, I am making the grand assumption the frame is tweaked. There is evidence of prior damage to some of the sheet metal. I believe the SF is back on correctly. The front sheet metal is straighter now then before I took it off. For now I am discounting a bent spindle since I had this issue before and have changed the spindles during this overhaul.

Anyone know a good place to take it for frame inspection? How much does this kind of thing run?
You can try jacking it in the air and dropping plumb bobs from different points on the frame, marking them on the ground. Then measure between all of the points and see if the dimensions match. This is what I did when I installed my frame rails.

Did you check and make sure that your coil springs are sitting correctly in the spring pockets of your lower control arms?
