Help finding window latch and side

It's difficult to tell precisely what you need based on its condition, but I recommend looking at our 26-243A and 26-244A for now. I believe these may be the parts you want, but carefully review our dimensions to verify that they match up.

Regarding the lock keeper, can you kindly tell me the distance between the two screw holes, measured from the center of each hole? With that measurement I can make a recommendation.
