It looks like I need to get a copy of the repair manual.
I keep hearing about it..

Keith,

A torsion bar unloader is definitely a mandatory tool for adjusting
them. It's basically a big grade 8+ U-bolt with a positioning nipple in
the base of the U. That nipple fits into a hole on the top of the
crossmember supporting the rear end of the torsion bar. A hefty
crossbar across the free ends of the U carries a 5/8"-3/4" grade 8
forcing screw. The rounded end of that forcing screw fits into a dimple
in the "pork chop" which anchors the rear end of the torsion bar.
Tightening the forcing screw releases the load on the 9/16" cap screw
which determines the angular position of the pork chop. Turning that
adjusting screw without releasing the load on it is a sure way to strip it.

The full procedure for adjusting the torsion bars is adequately covered
in the manual, though the explanation in Claude Brousson's paper is more
complete and readable, IMHO.
