If the mechanic is having trouble getting the toe set in the rear the solution is to slightly elongate the slots toward the rear of the car at the rear of the spring plates where the bananna arm connects.

As for measuring ride height, take some paint and put a dot on the center of the torsion bar covers at the front and rear. Measure from the floor up to the dot with your weight in the drivers seat and the maximum amount of gas that like to keep on board (I like 1/2 of a tank).

As for the front I'm not sure why the mechanic can't set the caster. Usually a bent strut results in a negative camber setting that can't be corrected.

As for settings I enjoyed the following set-up on my SC:
Front
Camber - 1/16 "
Caster 5 degrees
Toe -1.0 degrees
Rear
Toe - 1/8"
Camber - 1.5 degrees

Rear camber should always be more than front.
