Thanks Fraggle and welcome to the board.
I began the rear suspension work this weekend.
First one needs to disconnect the rear arm from the spring plate. Before fully disconnecting, I took an angle measurement with an inclinometer level:
to get the torsion bar out, I needed to pull off part of the rubber trim and peel back the vinyl black sticker on the rear quarter:
Then I could remove the cover plate on the rocker so the torsion bar could come out.
Bushings in both arms were deformed where the rubber had cold-flowed around the weight of the torsion bar supported car. These provided years of good service and deserve retirement now.
Down to the torch, vise and wire wheel grinder to get the bushings off and cleaned up:
As the directions suggest (and Flieger pointed out somewhere in this post), the arms required a few passes with a flat file to allow the inner bushings to slide on:
Last shot of bushings oriented loosely on the arms before I JB-Weld the bushings on and had to quit:
This job is very doable by the backyard mechanic. Air tools make it easier but there is just no rushing possible. The car is going to down for a while unless you can blast out 8 hour days in succession. And I have yet to tackle the frame bushing. JFairman posted that it is possible with the arms in the car and I am going to try that soon.
