Thanks for your post. I'll need to see photos of the existing hardware to identify the replacements you need. The stamp from the balance may only tell us the weight range the balance may be able to support but it doesn't help to identify the replacement needed.
Please provide clear photos of the top and bottom attachments on the balance.
Don't hesitate to reach out with any other questions.

My pleasure to assist! You window balances can be replaced with either the S378-29 or the S380-29. To determine which of these is the correct match, you'll need to confirm the depth measurement of the shoe.
Our 2840 stamp will support a sash weighing 23 to 28lbs.
Comparison of the S378, S380 and S385 balance shoes.
