Simonton window hardware replacement parts

A quick learner from Hamburg, New York says:
Need 10 left and 10 right complete replacement for what I believe what you refer to as a constant force balance system.
I have Simonton double hung windows, manufactured 7/11. Part # on existing is 801020.
Need exact replacement, including piviot shoe, coil spring and coil spring cover.
Believe that's available as a prepackaged unit ?
Also need to verify that your sash piviot bar, model # 26-378, is correct.
Please advise,
Thanks. Bill

The 15-199 pivot shoe is compatible with the 26-378 pivot bar. The coil springs would be the Series 160. There should be a spring weight number stamped on the end of the original coil spring. If you need the nylon coil spring cover replaced, see our 15-150D. We've related a few videos to assist you. Thank you!
