Replacement Balance Spring

Quick Learner from California
The hook for my balance spring is no longer in the correct position due to the balance shoe being broken. I'd like to just replace the whole thing, is there a definite way to know which of the 22 inch balance springs is the correct option?

"22 4 BSI OR"
The weight of the Bottom Window Sash is 21.5 lbs

This is the spring balance that I concluded was the fit for my window, but I am amateur and figured a pro could confirm it for me. Thanks!

We can replace this balance, but it will have to be a special order. Our Series 385 will not replace this.

Before we begin, can you just tell me how many you need? Once we know that, I'll send you an order link and price quote for that quantity. Keep in mind that 2 is our minimum, since this has to be specially made.
