We should be able to supply this balance, but we'll need more information to confirm. First, do you have an undamaged version of this balance that we can use as a reference? Perhaps from the other side of the window? It will be very difficult to ID a match from a damaged balance since so much has detached and fallen off.

If you do, I'd like to see a photo of the bottom of the metal channel, a photo of the top of the metal channel, and a photo of the clip, shoe, hook, or whatever bit is at the bottom. That will be a huge help. Thank you!

Here are pics of the unbroken (right side) window balance and where it connects to the window tilt mechanism.

Thanks again for your patience while we look into this. We can definitely replace this balance, but it will have to be a special order due to its design. Specifically, we'll be using our S770-34 channel balance but with the bottom clip swapped out for our 15-170

Does that look good to you? If so, can you tell me how many balances you need? Once I know that, I'll email you an order link and price quote for that quantity.

Looks like I emailed it to you on Monday. I'll send it again, but I also recommend checking your spam filter just in case it was accidentally flagged.
