Can you please help me identify the parts and part numbers I need to replace these window channels. I have several windows the same size. The length and including the clips is 29 inches. There is a number stamped on the inside 2920. See photos Thank you.

Thanks for reaching out. Based on your photos, I recommend our Series 377. This comes with a 19-018 top and 15-005 bottom. As long as those match up then I think you'll be good to go. Let me know what you think!
