Coil Balance Assembly
Thanks for reaching out! There is a chance that we can supply you with the replacement coil balance assemblies needed for your window. Although, I'll need to see photos of the hardware to identify the correct replacements. It would be best to see a photo of the hardware removed from the window to make the best possible replacement recommendation.
Unfortunately, I am unable to identify it based on the information provided, alone.
Please let me know if you have any questions in the meantime.
There are at least three different replacement solutions I could recommend based on the photos, however I'll need to see a photo of the entire assembly to confirm between each of those which is the correct replacement. While they all appear similar, they are not interchangeable as they have different measurements. With that said, you'll also need to have the hardware removed to confirm the dimensions and determine which is the right fit.
Take a look at both of the videos below for an idea on how to remove these shoes from the window.
