Help Needed for Ordering the Right Part

A home owner from California says:
I need a window balance 26 4 B.S.I.PA. There is no other print on the old part. The metal length is 26 3/4", including the plastic part, it is 28". Its width is 9/16. What size should I order? How long does shipping take? I live in California. If I need 5 of them, how much does the shipping cost?
Thank you,

We should be able to help replace this, though it will need to be a custom order. It's hard to make out what you have based on your pictures, though. I will need a clear photo of the bottom shoe and the metal clip attached to the end of the cord. Let me know!
