I am exactly at the same point as you, doing a front suspension overhaul and now I'm stuck with the torsion bars. I didn't mark anything while taking them off and the back key seems like it should be under more pressure then it is now. Any update on yours? Are you just going to have a mechanic do it?

 

I Ended up getting it done myself, I just kept messing with their position & rotating the front hex end, resting front control arms on jack stands I think is what made the difference (or it was the opposite & I removed the jack stands) sorry couldn't be more help but didn't want to ignore the question.
