Windows spiral balance and window holder

Thanks for your post! Your spiral balances can be replaced with either the (5/8") S600-36 or the (3/8") S900-36. To determine which of these is the correct replacement, you'll need to confirm the diameter of the balance tube.

I believe the part referred to as the plastic window holder may be the pivot shoe. If so, I'll need to know the measurement for the width and thickness of the shoe to confirm its match.

Please let me know if you have any questiosn.
