Unfortunately, the manufacturer of this Bonneville window balance has gone out of business. You may be able to replace your balance with our S795-31 channel balance. You would also need a 15-194 t-lock shoe to swap out with the default shoe that comes with the balance. You would go with the 31 D option to compensate for your stamping of "3040". This balance is mounted at the top of the window with a screw. Take a close look. Does this look like it would work for you?
