Can you please tell me specifically which balance I need to order? Only one side is broken but I suppose I should order two for the same window?

Hello, thank you for posting!
It looks like you have either our S351-22, with a 15-002 bottom attachment, or S390-22, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. The stamp option needed will be 2120.

Comparison of the S351 and S390 balance shoes.
Please let me know if you have any questions!
