NT window

Thanks for posting! The broken part appears to be your pivot bar. This basically allows your sash to engage with the pivot shoe, which is what does the tilting. It's tough to say for sure what you need without knowing the finer details of your pivot bar. Is there any way we can see an undamaged version out of the window? Can you also give us its measurements, especially the hole spacing? Specifically, I'd like to know the distance from the tip that goes into the pivot shoe and the center of the hole that is used to install it. Thanks!
