Torsion bar adjuster failure.

Redfish you described the procedure I use. No adjustment until the car is off the ground. You'll notice in Post #5 The car is off of the ground and on stands. The only pressure on the screw was from spring load.

I've had a very good experience with PST so far and purchased a lot of stuff from them. My understanding is that they offer a limited lifetime warranty on this part. I'll call them in a bit to see what they say.

These screws are pretty hard to cross thread, that's not to say you can't do it just that I am sure I didn't. Some additional info.. I started the bolt by hand threading then switch to Hand tools (a 1/2 inch ratchet wrench) no air or impact to continue threading the bolt thorough.

If you look at the bolt the thread collapsed in the center of the bolt and the damage to the threads occurred on removal as a result of the collapse. Take a look at the pattern on the threads, notice how they look worse closest to the center but become less damaged to the end.

Here is a picture of th thread in the Block so you can see it too. I used a bit of grease although I suppose anti seize could be used also.
