Window balance

Thanks for posting! The balance shoe in your window track reminds me of the 15-177 Coil Balance Shoe. You'll need to remove yours and compare the dimensions to confirm it is the right fit.

The compatible coil spring is the Series 152 Coil Balance, secured to the shoe using the 33-072 screw. There is a video tutorial below with instructions on how to select the coil spring needed for your assembly.

The 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and 15-145 Coil Support Barrel are used for the spring cover.
