I put bolts through the pad holes and clamped the heads into a vice to slot the back of it in a mill. Then turned them on their side and drilled them as you're suggesting. I have also heard some guys slotted the back by ganging a lot of hacksaw blades together. Check my gallery for a couple of pics.
