Hello! We can supply this balance, but it will have to be a special order due to its configuration. Before we go any further, can you tell me how many you need? Once I know that, I'll email you an order link and price quote for that quantity. 

As for your top sash guide, I believe our 18-171 is the replacement you want.

Sure thing! I'll email you an order link and price quote right now for 2 of those balances. That will allow you to add them to your cart as if they were a standard product and then you can continue shopping for whatever else you need as normal. The top sash guide and take out clips (16-002) would be sold separately.

Speaking of the top sash guide, you mentioned a spring in the top. I apologize for overlooking that detail in your photos; I had assumed that that was just an errant piece of metal. I didn't know it was part of the guide itself. Our 18-171 doesn't come with a spring and to be honest I've never seen such a spring used  this way. What does it do, exactly? I assume it braces the sash against either side of the window track. Could these springs be reused? We won't be able to supply them.

That is peculiar. The way this top sash guide is supposed to operate is that the top nylon fitting of the balance kind of notches under that tooth that hangs down from the top part. Does that make sense? This side profile may give you an idea of what I mean.

That's my hope, as well, but I can't say for sure. There is a chance you have a special version of the 18-171 that is designed to use this spring. The original installers may have had a good reason to go this way. That's why I recommend seeing if you can reuse that spring. I'm hoping that you can just pop them into the new top sash guides in a worst case scenario.
