Hi, I just replaced my channel balance but it is still not working and I noticed the plastic guide at the top of the window is broken. Can you help me identify this part?

Hi there!
Thank you for reaching out to us. Take a look at the 18-171. This looks like a match for your old top sash guide, but review the specifications and see what you think.
