The front T section of the frame is completely rusted out, so I guess it's possible that the beginnings of frame collapse at the front might have affected the steering. Hence the damper. At least I can hope it's that and not another yet-to-be-discovered problem.
Yes, I have a lot to do.
I spent part of today being defeated by a succession of rusted fasteners. I rounded off one of the inner seat belt mounting bolts, so I left that one for later rather than doing more damage now. The outer/lower seat belt mounting bolts are completely rusted and will probably need to be cut off. The master cylinder won't come off, and I don't now why. I can't get the steering wheel off. I think I'm going to have to get some more "weapons" for the battle against rusted fasteners. Maybe an induction heater coil ...
