Trouble Installing New Torsion Bars
With a busted T-bar, you have to think why it broke. I bet if you pop the LCA off you will find other damage; like the pin in the bushing is way off center, or the pin receiver is busted. This may put the T-bar socket out of line with the rear anchor, making installation quite difficult.
It's also possible for the front stub-frame to be out of alignment due to rust having separated the apron from the firewall, that apron supports the frame rail. If it moves so does the stub, and again the socket is out of alignment with the anchor. I have seen and owned several A's over the years that broke T-bars on account of they were asked to do the job of the apron.
Put the jack under the rocker pinch weld, and see what happens.
