Hello,

We actually have a conversion video that shows the coil balance assembly and pivot bar that we recommend to replace the parts shown in your photos. You can also find our return policy to send back the S140 balances that you purchased here. Take a look and let us know if you need anything else. Thank you!

For a 20-pound sash, I would recommend using one S159-9 coil spring on each side of the window.
