What's with auto body people? . . . .

Looking at the images of the green car, I am concerned that they might be right.
With the front end is down, I am concerned that the torsion bar mount in the rear is gone.
This is a substantial piece of the structure of the car. This is the foundation of the front suspension / torsion bar base.

This is not something that should be fixed with a small MIG welder.
