You've got the procedure right. If you can "flop" around the lower control arm the tension from the T bar is gone. Now, the bar may just slide out the back, or may not want to come out with a sledge hammer and the right tool. I don't think a clamp made of wood will do if its stuck, but you could try.

I believe the right and left letters on the bars are forward on the factory installs, and I just took a car apart a month ago and saw that as well. But the twist is the same either way. Good luck!
