replacement balance system?

With your parts still currently installed, it makes it a little difficult for us to be definitive in a proper replacement. Starting off with your pivot shoe, see if our 15-199 will work. There is a chance your coil spring may be able to be replaced with the Series 165. Looking closely at your photos, I can not tell if your support is a triple support clip. If so, you can use our 15-205 in place of your clip support. It's very imperative that you measure the thickness of your coil spring to confirm that it is 3/8". If it is not, then you will need to let us know so that we can continue to explore additional replacements.
