Torsion Bar Ride Height Adjuster troubles

sorry, I may have over simplified my answer - it clearly needs to come apart but also needs to be aligned before repairing... my bad. I didn't thing it was as bad as it is but did figure the back hole was "out"...
How could you weld the rear socket back in without the bar in there to keep it in alignment?I don't get that.
Just a couple of degrees of non-concentricity, and you will be pounding on the back end of the bar to get it seated. And then, how would you ever get it out?
