Thanks for contacting. Let's get you started with your replacement spiral balances. Based on the information you gave us on your balance we have come up with recommending our S600-15 as a replacement. You will need to know the color bearing of your balance when ordering this piece. As for your pivot shoe, there are two options we think it may be. Look at both our 15-046 and 15-173 . The 15-046 is 1/2" thick and the 15-173 is 9/16" thick. See which of the two would make the better option.
