These older spiral balances can be replaced by our Series 500, along with a 17-012 bracket that screws to the bottom of the sash. It looks like from your photos you'd need the S500-23 specifically, but double-check your dimensions to be safe.

Thank you Bob. I'll check dimensions, order a pair to see how they work and then take care of the rest of the house. Thanks again!
