Plumbing issues always require a minimum of 3 trips to the hardware store to resolve. The first trip before the project begins, buy what you think are the proper pieces. Trip #2 after initial disassembly, return or attempt to return those pieces from the first trip and replace them with the matching pieces of what you brought to the store as examples. Trip #3 after re-assembly begins, gather the parts to repair the broken fixtures that broke while attempting to tighten them, which all broke at about the 6 lb/ft of torque point :BangHead:
