My window balance is 35" in length. It appears to be like the S390 balance as the foot cap is 1 and 1/8" long. Thanks

Thanks for reaching out! It does look like you have the S390-35 given the length of your balance and the 1-1/8" shoe measurement. However to confirm, with certainty that this is the balance you need, I suggest double checking the measurement for the bottom shoe. Look over the dimensions from the diagram below. 

You'll need to select the 3440 stamp.
