The old storm door has holes that are 1 1/2 inches from top hole to bottom hole on center. The Center hole is 3/4 inches from each hole. The door's edge is about 7/8 inches to center of center hole.

I think you should check out our 40-032. This has the 1-1/2" hole center spacing that you need for your door.
