I posted in the Mechanics forum section about a missing component,
#5 in this pdf. A user suggested that I post here instead, that the spacer was common to other Shimano downtube shifting systems and that someone in C&V might have one. I'm not certain if it's common to purchase directly from other members through Ebay or some other means, but I'm hoping there is a way to avoid buying a whole new system for the sake of a single spacer. Thanks!
