Just get a 68x110 UN26/55 sealed unit and be done with it.
The inside measurement between the bearing races on the original spindle is 55mm. Through some searching around I gathered that I had a french set with thin cups, and a 70 would be the replacement size. Of course I am still pretty new to this stuff, so I could be mistaken. If I could fit a 68 spindle in my cup set I would be pleased. Can I?
I know it would be easy to buy a new BB, and it may be likely that is whats going to happen, but I am not giving in just yet. Plus I may end up learning something.
