What part is this and where can I find a replacement?
One of our shower handles isnt working correctly. it can spin all the way around, full water flow at 3 and 9 o'clock and stopped at 12 and 6 o'clock. Doesnt leak. i took the handle off and this small plastic piece was broken inside. Here is a picture of the other one that isnt broken. I took it to a big box store and they couldn't find a replacement.
