What do the install instructions say? I think these cups use the same tool as the cassette lockring, which is actually a nice touch by Campy.

Depending on the depth of the threads in the BB shell, you might be able to fine-tune the chainline with these cups.

I'd read through the directions, and follow them if they are specific enough. My second method would be to thread the DS cup in until the threads are just covered by the BB shell. Then I would test-fit the crankset on the DS spindle, checking the chainline measurement. If it's good, thread in the NDS cup and tighten to spec.

I don't see anything to indicate the BB width, but you can sometimes deduce it from the threading, which I don't see either. English threads would normally use a 68mm shell, italian would normally use a 70mm shell.
