Hello, thank you for posting,

Your balance appears to be a better match for the Series 770 channel balance. Take a look to see what you think! For the pivot shoe, do you have an undamaged version from a similar window that we could view? The right pivot shoe comes down to the exact dimensions. With the original missing, we cannot confirm the correct fit. We would need to see an undamaged version with written out dimensions of the width and thickness. 

Let me know!
