We can't figure out which one to order. We are the 3330 marked clearly but how do we know which one to order? I think there is a faint 70 marked on the metal. (Zoom in on one pic to see) Does that mean we should order the 370? Thanks for the help!!

Hello,
Take a look and compare our S350-34 channel balance with a 3330 strength option to your assembly. Thanks for posting!
