When securing the 10-324 shower sweep with rail to a metal shower door frame with the 33-071 screws, what drill bit and size should I use?

You would need a 7/64" drill bit. Be careful when drilling, since you don't drill into the glass or damage the frame. If you already have a sweep which is installed with screws, you could drill into the 10-324 sweep itself to match your existing holes.
