Hi there!
We can help but we'll need to see your bottom nylon fitting from a different angle to compare to our inventory.
Thank you!

Thanks for the additional pictures!
It looks like you have either our S351, with a 15-002 bottom attachment, or S390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need to remove and weigh your sash to choose the appropriate spring strength option. There's a chart on the S351 and S390's product page that shows you which option you'll need based on the weight of your sash.
If you have any further questions just let us know.
