Help selecting channel balance replacement for 2002 Cavco windows

Hello, Pam. I agree, your balance looks like a good match for the S385-27 with the 2640 stamp, based on the shoe size. I don't see the top fitting in your photos but as long as it's the same as our 19-005 then you should be good to go!

Please feel free to reach out if you had any follow up questions.
