Many thanks for writing in. The window balance system parts you are showing are for the old Metal Industries windows. The pivot shoe is our 15-180, while the coil springs will be Series 190. There is a spring weight number stamped on the coil springs near the pivot shoe they are attached to. The coil spring balance clip is the 15-181 for two coil springs and 15-186 for single coil springs. The coil spring bushings are 15-182. The pivot bar that people used for this system is 26-226.
