Marcus,
Use a 70mm spindle. Assuming that this thing has Italian
threading, that's what the make expected you to do anyway. If
it helps with th chainline, you might consider using a 1mm
spacer between the fixed cup and the BB shell. In fact, there
seem to hae been a couple of BB shell manufacturers who
expected you to use a fixed cup spacer. (Or some extremely
zealous mechanics facing the shells...)
Good luck,
