I would like to add that Dura Ace 10mm components are extremely rare parts, and knowing that this would probably be the case, I purchased two cogs and two chainrings, although all different sizes (alas only one chain - still unused), when I bought mine around '81. I purchased mine through Shimano USA (or is it Shimano America), and I would suspect that they might still have some laying around. Because of their rarity, I don't intend to ride the bike much once I build it, so it will be a show bike.
