I have received some helpful suggestions in the past on building up a 1973 Motobecane Team Champion and I am hoping for a repeat of this pleasant experience. I am using a Pat. 74 Nuevo Record rear derailleur on the bike but am having trouble with limiting forward movement of the changer. The Simplex dropout, while threaded for the Campy NR, has no forward stop. For the small cogs on the freewheel, this is not a problem, but the 22t cog (largest) meshes with the pulleys. Sheldon Brown suggested that I file a notch in the dropout but this did not work. Is there a washer with dog-eared flap that creates a stop? Any suggestions would be most appreciated.
Thanks,
