Turning torsion bar to lower rear?

Jack the rear wheels off the ground using the center of the rear housing.

IMHO

(and I'm sure there are 1000s who have done so with no visible ill effects)

Don't lift the rear of the car from the center of an 8 3/4, the housing is not as strong as the cast iron 7 1/4 and Dana 60
