1. What is your front chainline measurement currently?
2. Do
NOT use a Shimano UN55 110mm BB. They are asymmetrical and the spindle is a good 3-4mms farther out on the non drive side than they are on the drive side which would make your problem worse, not better. All UN55s are off by varying amounts but the 110 is off the most. I know this because I needed an asymmetrical BB for an oddball frame/build. Someone once posted a chart listing every UN55 length and the amount by which it was off center, but I can't find it.
