- find another car for parts or go to a junkyard

- drop the entire motor & trans as a unit; check thru both and rebuild as needed while working on the body; do the CV joints then too & check or rebuild the wheel bearings

- cut out the entire torsion tube assembly from a good car (or buy a tube) and replace it -- people have done this and posted pics here

Good Luck - you have a pretty rare car, besides the sentimental value
