To replace the coils, you'll need the Series 152 Coil Balance, which is attached to the shoe using the 33-072 screw. You'll need to check the metal coil for any stamps/markings that might indicate the springs needed to complete your assemblies. If there aren't any stamps, you'll need to obtain the exact weight of your sash and divide that by the total number of coils in the window.

The 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and 15-145 Coil Support Barrel can be used to replace the covers.
