OK, you are going to have to define what you mean by centered, let alone "originally." If you are trying to refer to the for/aft placement of the axle in relation to the wheel arch, then it will depend on the spring and 4 vs. 6" shackle flip combo. The flip will tend to move the axle forward, as the rotational axis is the front bushing of the rear spring. You can always use the zero rate to shift the center for/aft one inch.

As to the pinon angle, the flip in my case, on a K5, produced a -2* pinion angle which required either changing the perches, shimming too much, or going with a CV. I chose the later.
