I have an older storm door with Cmech 1 knob type set (not a mortise set; see attached photos). Interior latch tension spring has broken and latch no longer stays closed. 6 Holes in door. Two main shafts are 3 1/2 inches apart and screw mounting holes are 1 3/4 inches apart.Hoping to find a set that will replace existing set without any modifications to the door.

Hello,

Unfortunately, we do not carry an exact replacement for your handle set but take a look and see if you could adapt something like the 40-058 or 40-177 to work for you since they have the same 1-3/4" hole spacing that you need. Thanks for posting!
