window channel balance part

Hello,

We'd be happy to look into this for you but, unfortunately, the top fitting is too damaged to identify. If you could remove a balance from the other side or an identical window to show us the top fitting, as well as the clip at the end of the pulley cord, that will help us narrow down your options. 

I'd also recommend double-checking your channel length since a balance stamped with 2730 would generally measure 26" long, not including the end fittings. Thank you!
