9 windows have broken balance shoes

Thanks for reaching out to us. Your photos here show us a channel balance and a top sash guide. The top sash guide, at least, looks like our 18-124P, but I'm not sure about the balance.

I recommend looking at our S380-31 and S385-31 to start out. The only difference between these is the depth of the bottom shoe; you'll have to measure the shoe depth from one of our undamaged balances and then refer to our dimensions to confirm which one is the better choice.
