You would need to replace both the NR axle and the NR bb cups.

The Campy Nuovo Record double cranks would have had "Thick" cups with rifled openings to expel water.

The Triple crank axles were made ONLY for "Thin" Record cups. (No logic as to why this was the case.)

This means the center portion of the triple axle was longer.

So, because of the different axle proportions, using the NR cups with the Triple axle would leave what should be the exposed ends of the axle seated recessed too far inside the cups. And, it would also leave the left (adjustable) cup screwed way outside of the BB shell (at least an additional 5 mm).

Pre-1977 axle dimensions =

Nuovo Record Double: 29 - 49 - 32

Record Triple: 27 - 54 - 35

I tried a spare set of NR cups with a Triple axle and it was not a good fit at all - tended to pull the right crank too far inward, and snugged both crank arms VERY tight against the cups.
