This should help (scroll down):

Depends to a large extent on BB width (threading), whether cranks are double or triple, and whether they're pre-CPSC or post-CPSC.

(And thanks, Jim, for the lab work.)

(And also, Jim is correct in that there's no difference between Nuovo record and super Record cranks for the most part. In fact, for the most part, there's no such thing: They're all "Record" cranks. Only the chainrings differ between gruppos.)
