1 3/4 hole distance. The door handle has a curve to allow it to close and not hit the striker plate. Problem is that all the door handles are square and blocky and this hit the striker plate before closing. The door is about sixty years old so replacing door is not an option. Thanks.

Please take a look at our 40-052 inside storm door handle. See if this could be what you are looking for.
