Spring broke inside door latch causing latch not to operate correctly. Carch is 2 1/2 " high,1 1/4" wide, Hole centers 1 3/4", At present storm door has no readable markings. I believe by looking at the latch number (40-150) that I could possibly use it.

I agree, the 40-150 may be your best choice. We do not carry this exact type of handle.
