I recognize this. The manufacturer discontinued your balance system and it replaced with the Series 150 coil springs and the 15-140 pivot shoe. The other parts are the same: the 15-143 coil bushing, 15-144 coil bushing cap and 15-145 support barrel. When ordering the Series 150 coil springs, you will need to match the spring numbers on the old springs.
