48 coupe- car stance is not even all around

[Bolts]

Actually I discovered the way the rear end was hanging low on the driver side when I was getting ready to start taking it apart to fix a seal and do an axle swap. When I saw it, I was reminded that I had seen that the car didn't sit level with all the wheels on the ground about a year ago. The front end seemed to be slightly lower on one side.
The shocks are disconnected.
Chuck, I did replace some of the rubber mounting pads in the rear cross bar under the trunk when I replaced that rusted out section above the gas tank. There may be some slight difference there, but I think it's in the spring from the way the shackles look with the wheels hanging down when the frame is on stands. See the pics.

Other than replace the springs one way to adjust the body level is to install wedge shaped shims between the spring/s and cross member.
This is/was standard practice.
