Near the end of the CR On-Topic era, Campy introduced the last version of the Gran Sport crank, a 5-arm 116 BCD, whose rings interchange with the rings of the later Off-Topic Victory and Triomphe cranks. The late GS was often configured as a triple, and used long bolts and spacers. Sounds like the bolts may have been the same as those made earlier for doubles with a chainguard. The late GS triple and bolts for it would be another source to use in making up a Campy NR triple. As someone pointed out, an NR triple with long bolts isn't all that useful, as the smallest ring is 42T unless you can find a rare Campy NR 41T or buy a pricey current TA 144 BCD 41T. The late Gran Sport triple was a lot more useful, with a small ring as small as 35T.

The Stronglight 99, also frequently configured as a triple, used long bolts and spacers as well. Nothing wrong with this design. I've never heard of the long bolts failing, either Campy or Stronglight.
