This piece is not broken. The other side is. This allows the window to slide right over top of the channel balance

Thanks for posting. Your top sash guides resemble our sash guide pair, part 18-042. Take a look over the dimensions and compare them to your existing hardware. I am confident this is the replacement you'll need.
