Turning torsion bar to lower rear?

test it out... put a block of wood and jack under the pass side front lower a arm.

before you jack it up measure symmetrical points on all 4 corners. Like maybe outer most bumper bolts or some tape on the outside of the bumper. then raise the pass front a 1/2" then measure the change on the other corners. you might be surprised!
Put the jack under the frame rail, this will simulate the height change with torsion bar.
