A workshop out of the floodplane #4: Delta Fence on the craftsman table - Where to drill the holes?

as I mentioned in the previous post, I started working on refitting my Craftsman 10” table saw with a Delta T2 fence, based on Jaime’s blog posts. I have everything measured and marked but I’m not at all clear on how high the front rail (or the rear rail, for that matter) should go relative to the table. Jaime mentioned drilling the holes offset vertically from the manufacturer’s holes, but he just said “a bit” I didn’t see any other real indication of how to do this. I don’t want to mess this up, so I need to get an exact idea of where to drill.

Here’s the rail set on top of the saw, but aligned horizontally. If anyone has a good way of determining how high the rail should go I would love to hear it.

Also, any recommendation on how to drill the counter sinks – what is the right kind of drill – some how the regular counter sink bit doesn’t strike me as the right tool. I expect it to be worn down and dulled by the metal rail. I’ll do some research on that, anyway.
