Look at the torsion bar socket misalignment in this picture. The back of the socket is facing UP. To me, that says the frame in FRONT of the jack stand is drooping DOWN. Here's what I would try. Get on the frame rail well in front of that jack stand with your floor jack. You'll need a 2x4 or 4x4 to reach it of course and jack up on the front of that frame rail then check the torsion bar socket alignment and see what it looks like.
