Greetings, Gary. I see you referenced our S385-33. It does show some similarities to yours. You just want to make sure that the depth measurement of your bottom shoe matches up with ours. If everything is correct, you can go with the 3240 stamp option which holds a sash spring weight of 23-28 pounds. You also want to confirm the metal length measurement of the balance. Usually, if a stamp begins with "32" it tells us that the metal portion of the balance is 33".

Thanks Paul,
I am sending a photo of a plastic part that screws into the top of the window.
Can you supply these?
