Actually, the 'correct' way to fix this is to have a new housing done, with unequal length axles. The rears are off center slightly to the pass side so that the shaft has a straight-shot on the pinion yoke, the pinion being to one side of the ring gear. This is more 'defined' when using a 9", fyi. The reason this is done by GM is so that the axles are the same length, less parts to manufacture.
Some correct this by making the rear overall shorter, and using a spacer on the drivers side. Others just live with it the way it is.
