It'll be english threaded 68mm, like all LOOKs as far as I know. Measure your chainline now - if it's good get a BB with the same spindle length, if not, compensate accordingly. If there's a Shimano or other JIS BB in there then remember that with a Campag or other ISO BB the cranks will sit 4.5mm further in than with JIS.
