Thanks Paul,
I think those should work just fine. I can't wait to get these windows working right!
It was no problem at all, I was glad to help. Let us know how the balances work out for you!
They did work for me, but as mentioned there is extra lateral play in the window. For me it has worked fine for the last year. in fact I'm ordering some more right now for another window. I just make sure the window is closed with 2 hands or it is closed from the center. I could see how that would be unacceptable for some.
Other than making some from scratch or finding some old replacement parts this is the best option for me.
