So am I. Do you have a C-record crank and a C-record BB that is correct for your frame? If so, they should be a good match. Why do you have a problem in the first place?
BTW, I have used my C-record crank with a Campy sealed ACH-111 mm bottom bracket, with very good results. Those are still around from time, and should be pretty cheap. Lickton should be able to tell you more about what modern BB should be a decent replacement for the ACH-111 mm.
