These Simonton coil assemblies are no longer made but we're fairly confident the 15-259 Coil Balance Pivot Shoe will work in its place. The existing pivot bar will not be compatible with this shoe, so you'll also need the 26-083 Pivot Bar.
The compatible coil spring is the Series 159 Coil Balance. To determine the correct springs for the replacements, you'll need to look for a stamp/marking on the coils. If there are none, please see the video tutorial (tagged below) for instructions on selecting the correct coil weight option.
To replace the coil balance supports you'll need the 15-256 Coil Double Support.
