1. I am looking to find the correct pivot shoe replacement part. I have attached pictures. The windows are Thermal-Gard Windows from 1982.
2. The reason I need the placement parts is that many of the pivot shoes have cracked off, especially in the top windows that don't get a lot of use. They get stuck and when I apply too much pressure to try to slide them down, they crack off. Can you suggest a product to use that will have keep the pivot shoes sliding easily. Perhaps some sort of Silicon spray?
3. What type of spiral balance charging tool
