I've had to reweld several of those because they come detached inside the k-member.

The torsion bar is not and was not designed to retain the control arm. The factory rubber bushing is a press fit to the pin and to the arm. That press fit and the strut rod is what is supposed to retain the arm. Caster will dynamically change under accelleration and braking if that press fit is not retained. If you take the torsion bars out you can better see what I am talking about. Remove 1 bar and then pry on the arm at the pivot pin. it will start sliding off the pin.
