my house was built in the early 60s in Florida. This is all that bis left of the sashes, they are non-tilt windows, I have two, and all balances are in bad shape. any help would be great.

Hi there!

Thank you for reaching out to us. Can you show us a photo of how this balance connects to the sash at the bottom corners? 

I'm thinking our Series 500 spiral balance and 17-012 bracket may be the way to go. We've used this setup on old wood windows and find it to be a reliable and straight-forward solution but I'd like to see photos first just to be safe.

I should have specified, these are old metal windows. I want to say early 60s

Thanks for clarifying. I believe you have a very old Air Control window. The bottom nylon sash clips are the 17-014 and 17-015 . The balance system will be Series 300 with either the 15-011 nylon shoe or the 15-020 nylon shoe. In order for us to determine the best match, can you remove an undamaged shoe and show us some photos?
