May seem like sacrilege to some but I'm considering using a modern cartridge bottom bracket with my 1982 campag cranks, I'm going mad trying to buy the correct bottom bracket in useable condition for a price I consider reasonable. So my understanding is that I require a jis taper as campag didn't go ISO til later and jis is closer to campags taper, 115mm axle length with drive side offset. I'm looking at shimano un55, has anyone done this?
 
Most of my Campag cranks run on Shimano cartridge BB's. I know people say you shouldn't but they seem to fit OK for me and I haven't had any problems.

I've now fitted a 115mm shimano Un55 bb and it's fine, prob could have got away with a 113mm, got about 10mm chain stay clearance each side. £9.49 delivered.
