Hello! Your part looks similar to our S377-31 channel balance. This comes with a 19-018 top and 15-005 bottom nylon fitting, so as long as those match up then you should be good to go.

As for the top broken piece, it could be our 18-042. This is the top sash guide designed to go with the S377-31. I recommend removing it from the window to confirm.
