Thanks for posting. If your balance channel is 3/8" wide, see our Series 800 replacement channel balance. I think this could be a good match. I'm not sure about the broken top sash guide in your first picture, but chances are it's a match for our 18-036. I recommend removing yours and comparing its style and dimensions to our pictures to confirm.
