Window Balance Needed

A home owner from Casa Grande, Arizona says:
I need assistance in knowing what to order. I have attached 2 pictures of the current balance that needs replaced. The only identifying info we can find on the balance is: 34-3 EA2 CMC 5. The metal part is 35 inches.

It's hard to tell from your photos what balance you have. That stamp only tells us the strength of the spring, it's not a part number or anything. The only way to find a matching balance is to compare specific physical details. I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
