Thanks for contacting us. Our customer service representative tells me that your balance is actually 35-1/2" long. Can you confirm? If it is, it will need to be custom made. Can you tell me how many you'll need? Once we know that, we can send you a price quote and custom order link.

I'm sorry, I'm not sure what you mean by "50 spring" and "40 spring." Can you specify? Are those stamps? If so, what is the complete stamp in each instance?

Yes, the stamp on the ones I have say 3640 and 3650.

yes its the spring size, the one I have is stamped 3640.
But my customer has a window that will not stay up. So Id like a little heavier spring for that window.

That stamp is actually a little weird. If it starts with "36," then it should be 36-1/2" long, not 35-1/2" long. If your metal channel is definitely 35-1/2" long, then we will need to know the weight of the sash that each type of balance supports. You will likely need a new spring strength calibration.
