Greetings:
I need the black plastic cover that fits over the fixing bolt at the top of '70's Huret rear dérailleurs. Mine is a Duopar, but from the pictures in the Dancing Chain it looks like the same part was used on the Challenger and Success dérailleurs.
Will happily pay for the part, or for a parts donor derailleur. Or, if you are looking for something, I will gladly check the parts department for a trade.
Thanks,
