Yeah, I've got some UN-7X's sitting around, and noticed that the 110 was asymmetrical and that it's a 107mm BB for chainline purposes.
If I've gotta get a new BB, I may just sell the Campy crank and BB on eBay, and cobble something else together. I've got lots of Shimano-compatible (JIS) bottom brackets, but no other Campy-taper (ISO) bottom brackets.
