Window balance replacement

Hi there. I believe we can help you with a replacement, but it will need to be special made due to its configuration. Before we get into more detail, we'd like to have you send us over another photo showing the clip on the bottom balance shoe. We'd also like for you to confirm the metal length of the part. Lastly, if there happens to be any stamping or marking on the balance, please send us a clear shot of that. If there isn't a stamp, we will need for you to get back to us with the exact weight of your sash. Thank you.
