Window pulley replacement

Question

Markings are 26 5 BX CMC stamped on pulley channel. I am not sure how old the windows are.

Would appreciate some guidance to see if it's an easy replacement or better to call a window company.

Thanks in advance!

Thanks for your photos. Based on what I see here, you have either our S385-27 or S380-27, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
