I am just going to go over where you can find replacement door hardware for G-U, Eagle Biltbest & Hurd Doors. Emtek is the name, and mix and matching is the game.  Just head on over here for starters. Configuration 2 is where you would compare Emtek's measurements with your own. It looks like this..     The 2 center holes (3 5/8"" CC) are the most important.  The 2 outer holes are where the screws or bolts go through the door to hold the plates in place, so you could re-drill those if you really needed to.   So after you have compared measurements. THEN you get to the fun part! Choosing your style and mix and matching.
