Uneven LCAs help

Is it possible that the REAR axle is somehow affecting this? Don't discount ANY detail. Tire size and pressure, the floor is perfectly level.

IS IT POSSIBLE that something (a rear leaf) has changed / broken in the rear?

Because "we can't see" what you see, try to "play" with the clocking. Remove the adjustment bolts and nut plates (I don't remember the tech word, LOL) and pry on the levers to see if you can get "one more clock" on one side.

ANY chance you "forgot" and have mismatched bars? Easy to do with the "junk" I have around here LOL
