I wonder if anyone can help me. I have a road bike equipped with a vintage Campagnolo Mirage group set. My problem is that the right brake/shifter is broken, it's the plastic housing that has broken. Does anyone know where I can get vintage parts, I'm not entirely sure of what year the group set is, I'm guessing it is around circa 1996/7 it's the 9 speed shifters. I'm in MA, USA Thanks in advance
