MI window tilt latch

The latch you have here reminds me of our 26-244 Tilt Window Latch; its opposite handed version is the 26-243. To confirm that these are the correct replacement, you'll want to find an undamaged latch and compare the measurements shown on the diagram below. 

If the dimensions are not a match, please let me know the written measurements from your existing latches. It is a bit difficult to read them from photos of measuring tape.
