Unfortunately I couldn't find an original Campagnolo bottom bracket set with Italian thread 36x24T and spindle 70-P-120 yet, but I've bought this set and it comes very close. The treading is Italian, of course, but the spindle is 70-SS, 110mm instead of 109mm needed. So, the length is almost what I need. Now I just have to test how the chain line will be. Perhaps I can get the right setup with a washer behind the RH cup or behind the sprocket. Otherwise I have to keep my eyes opened for the ideal set. I will do that anyway.
