Please help me find the proper replacements. My old balance channel is 35" long (excluding plastic end pieces) and has the stamped number 3440. From your site info, I think I need a 15-002 shoe, but I don't find a picture of the correct top piece (although I see it in your info videos). See IMG_6650.
Also, I need the plastic guides for the tops of the window tracks. See IMG_6647.
Please provide me the correct replacement balance assembly part number and your pn for the window guides.
Thanks,
John
