From what I can see in your photos, I believe you may be able to use our
S765-21 balance with a 20-9 spring option. For your pivot shoe, see if our
15-046 would make a good match for you. If these should not be the parts you need, I would encourage you to get back to us with some additional photos of the parts removed from the window.
I also have placed a list of replacement parts that are commonly used for Silverline windows on the upper right hand side of this page for you to take a look.
