torsion bar system, i need help

If you loosen the lower control arm nut, the one that goes through the k-frame, that adjuster arm that sticks up can be rotated back into position. You need to spray all that down with WD-40 or PB Blaster to break the rust free. When you get it all together the lower control arm nut on the k-frame, leave that a little loose and give it its final tightening when the wheels are on the ground with the weight of the car on them.

If you are looking to get the other torsion bar out, the one that is not broken, take off lower control arm nut at k-frame and the strut rod nut at k-frame, remove clip at rear of the torsion bar, put a piece of wood on the LCA and whack it with a big hammer to drive the bar back. Again put some PB Blaster or WD-40 on all the rusted parts.
