Replacement needed for a window channel guide

A home owner from Santa Fe, NM says:
I have a non tilting window that the pulley broke on one of the channel guides. The metal channel is 27 inches long x 1/2 wide. The markings on the channel are 86 26-4 FC5 CMC. I have more pictures if needed. Which channel should I order. Thanks for your time.

This looks like our S385-27. Check it out and let me know if you agree. Make sure to carefully compare the nylon attachments to be sure that they're a match.
