Hello,

We'd be happy to help but we would need to see the front of the bottom fitting where the pulley clip extends from to narrow down your options. We'll also need to know the numbers stamped on the metal channel. If there is no stamp, we would need to know the exact weight of the window sash to determine the spring strength needed for your replacement balances. Thank you.
