Window balance stamped 3370

Thanks for contacting us. I believe we can replace this, but it will have to be specially made. While we look into its availability, can you first tell me how many you need? In the meantime, please bear with us a little longer.

I wanted to add to my request from earlier before we go any further. Can you show me a picture of the metal hook that was at the end of the cord? That will help us in our search.
