The Campagnolo BB that came off was 70x113. But for whatever reason I feel like I'm supposed to put on a Shimano UN55 70x110.
Thanks for all the advice everyone!
We need the Shimano model number off the crank. It will be on the inside of the crank arm. Or you could Google with that info - There is a Shimano table showing the correct BB width for most cranks by model.
