out of commission, cant drive my dart anymore

ok, so to take the tension from the torsion bars is as simple as just putting a wrench on those bolts and turning them counterclockwise? They dont have any lock nuts on them or anything? I will spray them with penetrating oil for sure, but is there any chance they will brake off when i start turning them making the torsion bar unload all at once? Also, as far as removing the torsion bars, do i have to do this? can i just slip the lower control arm off them or do they have to be removed from the car? if so, do i just need regular old circlip removal pliers? THEN, what happens, you have to beat them backwords to get them out, towards the back of the car or?
