Need this whole rod replaced

Hello there. I'm confident we can replace this channel balance, but we need to see the nylon attachment on the other end of the metal channel as well. The combination of attachments determines the right replacement. Many thanks. 

That's perfect, thanks. This looks like either our S380-28 or S385-28 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Compare both with your old hardware to see what matches best. In either case, for a stamp option choose 2740. Let me know if you have further questions.

You're very welcome! Please don't hesitate to reach out if we can be of any further assistance.
