It’s all how you want to start the process, with the rear mount so severely worn (and not seeing the front mount condition which I can’t imagine is much better), and seeing you like the ride and stance, for nominal cost you can just replace all the spring mount bushings, and shackles/shackle pivot bushings and see how that puts everything, you need all that put in good order in any direction you go, and I may well set things right.
If not then go the new spring route knowing it was necessary, with the bushings so worn I think it premature to speculate on the springs being twisted…..

Re blocks lowering or lifting? Semantics really….say it how you like, yes the blocks are “lifting” the axel in the frame, which “lowers” the truck… I chose to call them lowering blocks"…..
