Yep, agreed +3. If you were in the DC area, we could resolve this over less than a 6 pack. Where do you live? You may find an equally cooperative C&V'er in your area with the requisite assortment O'spindles and tools to juggle parts until things line up properly.

Failing that, head for the best local LBS with a real mechanic in the shop who can do the same thing. My guess is that the BB on there is a 127/128 and you need a 122 (although sometimes an asymmetrical 120 will fit)

Failing THAT, PM me regarding those three vintage triple cranksets I have that would pretty much match what was on there in the first place.
