Torsion Bar Help Needed Quick!!!!

If I can't retap the block in the lower control arm. How would I go about removing it. I am assuming I will remove upper control arm,tie rod,sway bar, and shock. I figured I need to get the lower control low enough to remove the tension on the swivel part or i will never be able to get the block(where bolt threads into) out. What about the tension on the torsion bar?
