If it was ME, what I would do is loosen the K frame bolts and try to get the torsion bars in and "everything else" in the right place, then cinch down the K frsme bolts. Might not be the "correct" way, but that's what I'd try.
Yeah that's about what I'm about to do. Tough being alone with all the up and down involved. I can see me tightening one bolt, checking both TBs, tightening the next bolt, repeat.
I should have done that first thing. Four points have to be right before torquing the k-frame, the TBs, the transmission x-member, and the steering column. I will know the next time, as unlikely as that is.
FWIW, I had the torsion bars out of this car before I took the k-frame out, and they slipped in and out with no problems. So it used to be straight and this is all a problem of my own making. Like I said I'll know the next time.
