Torsion Bar Ride Height Adjuster troubles

How did it get that way? did you remove the torsion bar yet? Or is this after you removed it and are putting it back together? Where's the adjusting bolt? Is the frame where the back of the torsion bar mounts solid or rusted out?

I would start with spraying/soaking them in penetrating oil then trying to pry with a pry bar to see if you can get it to move.

If that doesn't work you may need to remove the lower control arm, clamp it in a vise and work on getting the center to pivot. Once the center pivot frees up, the tab that the bolt end seats on can move.

Where's the adjusting bolt for the torsion bar? Is it not seen in the angle of the picture, or has it been removed? The end of the adjusting bolt should seat in the pocket of the arm...
