It looks like it says 932 on the one that is broken. It appears to be all one piece when I took the one out that wasn't broken
The coil is 1/2 inch

Hello,
Your photos appear to match the 15-180 balance shoe, which is compatible with the S190 coil springs. Take a look at the product's specifications to confirm. Thanks for posting!
