man, this thread just cannot slide into obscurity. . .
dake13 here's what I'd do.
first a few questions,
how old is the bike? what is the rear spacing ( 126mm or 130mm or if really old 120) ?
we need pictures here.
But what I'd do is build it full campagnolo gruppo.
A bike like that should be Super Record gruppo unless your going to build
with modern ERGO gruppo.
There is no difference in the Nuovo Record and Super Record crank arms, the difference
is the chainrings, and you can get those on ebay for less than $100.
spindle for BB will depend on the BB cups you use, check out Bicycle Classics they have
a good BB chart (as does Phil Wood).
