RB, Even if you change the shoes instead of relining the ones you have, you shouldn't need to change the anchor bolt direction. The shoes are all made to the same specs, thus the mounting holes are all in the same place. There would be no need to re-center them on the backing plate.
Unless, of course you a re a nit-picker, you will not notice the 1 or 2 thousandths difference.
If you get crazy and ask for trouble, I have the Ammco 1725 tool that you can borrow to save your skin.
