Thanks for reaching out to us. I'm afraid this isn't enough information for us to ID your roller. We'd need to see photos of an undamaged assembly removed from the window in order to help. Let us know if that would be possible!

Thank you kindly for the photo. We don't have a sliding window roller with your exact specifications. The 87-163 and 87-164 are similar in design though. Take a look at the specifications and see what you think.
