Lift Arm Hitting Torsion Bar

[muz123]

I noticed that the rear shell of my 3023 was difficult to close. After looking around, I noticed the lift arm was hitting the front torsion bar on the door side, as it went up (or down). This was also causing the curb rear shell latch bracket not to straight up and down, or perpendicular to the ground. The threads that show how to adjust the lift arm do not seem to apply here. I'm stuck!
