Hello,
I had a pivot bar rust and need to replace the channels as well. Would you be able to look at the attached channel pictures and recommend the right replacement channels and replacement pivot bars too? The existing channels just "clip" into holes at the top of the window, which my pictures don't show. I can't tell the brand of window or other parts, but found your website and videos helpful and wanted to see if I could use your parts to fix my window. I appreciate your time and help.
Regards,
Keith
