K-frame alignment?

George Jets said
Cross check the K member location with a tape measure off matching holes in the rear sub frame to make sure the K member is installed square to the car.

Did that already, measured to the front of the frame rail/rad support. It's square, but it wouldn't hurt if I could figure out a way to measure it diagonally. The shape of things under there make that harder to do than it should be.

With no engine in the car, I would move those front jack stands to the trans crossmember sub frame. To help the front of the car droop down into alignment.

Those cars flex all over the place when jacking them up.

First clue right now with the way you have it, do the doors hang low when you try to close them? If so, moving the jack stands to the crossmember sub frame will help to pick up the rear doors so they close better > body in alignment.

It's got an engine in it now, that is an earlier photo. Once I get past this torsion bar issue I could be ready to start it up in about a week of evenings.

The door does seem to be sagging a little bit but it's not a lot.
