Thanks for writing in. I'm afraid I can't really say what you need without any more details or pictures of your current spiral balances. The only difference between the Series 600 and Series 900 is the diameter of the tube. For spiral balance identification, see the video below. For your pivot bar, that patent number has been associated with our 26-125 in the past, but look over the dimensions to see if it matches.
