Need to replace my top sash guide

Question

This a General Assembly block and tackle style window. I am looking for a replacement for the piece in the photo. The piece I need is the off white colored cap with the single screw holding it in place.

My apologies. This is a general assembly channel balance sash guide I believe. 1/2" .can you confirm and let me know if you have a replacement part or something that would work?

Thank you!

Thanks for posting, Brian. This top sash guide is no longer made, I'm afraid. It was discontinued a long time a ago. A substitute was made, but then that was discontinued, too. Fortunately, yet another replacement was made: our 18-066. We do have this, thankfully. Look it over and let me know what you think.
