Thanks for your post! This window balance shoe is similar to the 15-180 Coil Balance Shoe. To determine if it will be a fit in the window track, carefully review and compare the dimensions.

This shoe is compatible with the 26-040 Pivot Bar.

To replace the balance springs, you'll need the Series 190 Coil Balance Springs. They are anchored to the window track using the 15-181 Double Support Detent Clip. To determine the weight option for your assemblies, you'll need to look for a stamp/marking on the coils. If there aren't any, please take a look at the video tutorial below.
