Pretty sure it's been discussed before but searches here found nothing. I have seen a few 70 Challengers that sat lopsided from the factory. I vaguely remember this might have been isolated to one plant or another (Los Angeles?). What actually was the reason for this and how have others gone about making a fix? Were the leaf spring front hanger mounts not installed at the same height, or drilled wrong on one side? Has anyone actually had an e body with this issue on a frame and made the measurements to confirm this?

If it has SS springs, or XHD spring package they would sit jacked at an angle, I sure don't recall anything else but im a young'un...

Look in the SM, it actually tell how to measure the rear ride height. But the front has to be right also.

I'm talking stock from the factory, stock leafs, etc., front end set up at correct even heights. Drivers side sits a little lower than the pass side, when viewed from the rear. I've seen more than one do this.
