Hello,
We'd be happy to look into this for you but we'll need a bit more information to narrow down your options. First, we'll need to confirm the stamp code printed on your metal channel, which looks like it may be either 27 1/4 or 27 1/2. I'd also recommend double-checking the length of the metal channel, not including the end fittings. Please also write out the exact depth of the bottom fitting. Lastly, we'll need to see the connecting point between the spring and pulley inside the metal channel, that would help us confirm if our stock balances could work for your repair or if they would need to be special ordered. Thank you!
