The size of the spring is not usually the culprit for that kind of damage. I see you ordered a balance with the 31.25-3 stamp option. What was stamped on your original balance?
A home owner from Georgia' says:
Tom the only stamp I see is 3672 Caldwell cm

Ah, I see. Typically, that stamp corresponds to the 31.25-4 option. I highly recommend weighing your sash on a scale and referring to the chart shown on the S745-32 store page to confirm.
