Rear end alignment issue 1969 cuda

And the Super Sleuth award goes to ——Bodyperson!!!
Spring was unrolled some on the front of the side that was the farthest back. Got under there with my flashlight and noticed the passenger side (longer measurement) was unrolled about 30-45 degrees. Never would have known to look for that. Pictures aren’t very good

Can it be rolled back with some heat, or do I just live with it, shim the other side, or replace it?

Thanks to everyone, I never would have figured this out on my own!
