Universal transfer punches or Transfer punch sets:

With the holes drilled in the top surface of one plate you would align it to the edge of the other (using clamps, 90 degree blocks etc.) put the correct punch into the hole and 'transfer' the centre point onto the edge surface.
This is exactly how I would go about it, if you take your time you could drill and tap yourself, just take your time, especially when tapping and I think you'll be suprised how easy it is.
