    Replacement BB cup for UN-73

    SOrry if I posted in the wrong area but does anyone know where I can get a new BB cup for the non-drive side of my UN-73 bottom bracket.

    For the UN-73 they made the non-drive side cup PLASTIC and I've already chipped a few pieces off plus I've had to clean it all the time due to the plastic flexing and getting more crap in the threads.

    If I could just get a metal BB cup for the non-drive side that would be great?

    Anyone know where?
