I have been watching this thread with interest. There are a lot of good responses here, but it is very difficult to diagnose from a distance.
It seems that the main problem is evidenced by steering linkage striking the torsion bar and headers. It is a problem of two objects trying to occupy the same space.
The steering linkage was designed to operate in a plane, i.e. the moving parts move in arcs in a plane. Something has obviously shifted the plane of movement of the linkage.
There has been note made of physical problems with the K-frame. There could also be problems with the front sub frames and LCAs.
I believe that the car body needs to be checked for "trueness." That could be done on a body shop frame machine or you could get a rough idea with jackstands, shims, and bubble levels in your garage.
Something is obviously tweaked. Gotta start with the basics.
