Hi there, Cherylyn.
Thank you for reaching out to us. We can help supply the balances shown here but it will have to be a custom order due to its configuration. What I mean by that is the pulley wheel built into the bottom fitting itself, as well as an extended cord travel and a metal channel length ending in 5/8". I will just need a bit more information to help get this moving for you.
Can you confirm if the metal hook in your last photo is our 62-106 or 62-105? They're not interchangeable so it is very important we know which one you have. Can you also tell me how many balances you're looking to order? Finally, can you confirm which stamped balance uses which hook?
I also wanted to mention that it's a bit odd for two windows of the same make to use different configurations, even if they are different sizes. However, if they've worked all this time then I see no reason to change.
