Need springs for my old old channel balances

A quick learner from Texas says:
I need to replace some broken springs in some balances which are off of some all wood windows with double pane glass (pretty heavy sashes).
The channels are 24.5 inches long and the actual width of the opening that is the channel is about 9/16

Unfortunately, these balances aren't made any more, so we will not be able to offer an identical match. You might be able to substitute them with our Series 500 5/8" spiral balances, along with a 17-012 bracket. This combination has been used in wood sashes since the 1940's. Do you think you could get this hardware to work in your window?
