Please provide the replacement model for this balance. On bottom left of flange it shows 1131. On right side it looks like U70 08. Thanks!

Thanks for writing in! Based on the provided stamp, it appears you'll need the 24-1133 Andersen Sash Balance. These are made to replace balances stamped with a 1131 and 1133. They are not designated for any particular side of the window.
