Reliabilt? Pivot Shoe and Balance

Greetings. From your photos, it appears you have the 15-180 pivot shoe that uses Series 152 coil springs. There is a number stamped on the spring that should tell you the spring weights you need; or you can weigh the sash, give us that exact weight, and we can figure the correct coil spring weight stamped. For the sashes not working, you either need to replace the broken pivot shoe or coil spring, or both if both components are damaged.
