Spring balance for single hung window

A quick learner from South Lake Tahoe CA says:
My client has a window with this balance in it and the string broke. The whole part measures 26", the string (however broken) measures approximately 37". I just need to order whatever parts you recommend to fix the window. I've attached a pic with the part number. I look forward to your response.
Thank you,

You would need to replace this whole balance. I would be happy to make a recommendation, but we need a bit more information. First, can you show me both ends of the metal channel? Specifically, I'd like to see if you have any nylon attachments on either end. I would also need to see a picture of the piece that broke off the end of that cord. Thank you!

Thanks for the response! Here's more pics;the first two are of the end caps, and the second two are of the two ends of the snapped cord.
Thanks again,

Thank you. Based on these new pictures, I would recommend our S385-27 channel balance. This comes with a 19-005 top and 15-004 bottom pre-attached, so just make sure those match. I would also recommend a 2640 option, which can carry a window sash weight of 19 through 26 pounds.
