Hi, I am in need of a viking window balance. It is 1/2" (9/16") wide and 35 1/8" long. The only identifying marks that I can see is the number 3430. I believe the window was made in the year 1996.

Hello!

It looks like you have either our S351-35, with a 15-002 bottom attachment, or S390-35, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 3430 spring strength option. 

If you have any questions just let us know!
