Ignore the information in post #44.
Again, older Campy spindles are much, much closer to ISO than JIS. Although they may never have been given proper designation they are so close that they may as well be called ISO. Seriouslys jebs5, your more than welcome to role on by the 33647 and take a look for yourself.
AndyK: I checked both pre and post CPSC (1977) cranks with a 111mm spindle. Both clear the frame with plenty of room to spare. I think the need for a 114.5mm spindle is due to the wider CPSC front derailleur. If a FD narrower than the NR/SR w/ the raised lip were to be used I see no reason why a 111 wouldnt work.
