Campag Centaur BB compatiblity

Afternoon all.

Is there any definitive answer on what BB I can use for a Centaur crank apart from the obvious Campag one?
I need to put a 121-125max bb in a frame and I really want to use my Campy crank but can't find an ISO(I believe that's the closest to Campy) bb in that length.

It's been on a Mavic sealed job for 30 years and working fine, but for various reasons I'm not reusuing that BB.

Someone I spoke to today said just use a JIS it'll be fine, but if anyone knows for sure be good to know.

Any help gratefully received.
