Thanks for reaching out. Before we move forward with a recommendation, I'd like to confirm that these balances are for two different types of windows.
These aren't interchangeable so I'd like to confirm to ensure we are recommending the correct replacements.
Thanks for confirming. In regard to the coil balance assembly, I recommend taking a look at our S140-11. Carefully compare the dimension to confirm that this is the right fit for you. I am confident this is the replacement you'll need.
The other assembly appears to be an older discontinued shoe that is no longer available. For this, we typically recommend our 15-192 Certainteed pivot shoe to replace your Simonton brand part but you may need to shave down the aligners from the shoe to install it into the window. Take a look at the dimensions to confirm if it may work for you.
We are now recommending the 15-259 pivot shoe, which should fit well in the track, along with the S159 coils springs and 15-255 single or 15-256 double support. To use this assembly, the original pivot bars would need to be replaced with our 26-083. We are still in the early stages of confirming if this replacement is a good long-term solution but we have high hopes that it will work with little need for modifications, if any. Take a look and if you decide to give it a try, we'd be eager to hear how it works out for you.
