Hi there,

My window broke and these came off each side. I don't know why each side has a different stamp, but I need one of each? To put my window back up

Hello,

It looks like you have either our S351-32, with a 15-002 bottom attachment, or S390-32, 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 3130 spring strength option for your replacement balances. Thank you!
