A used hub from an auto salvage place might aleviate any concerns. If there is the slightest concern the races will not end up square especially. A lot cheaper than trying to deal with a problem far away from home someday and somewhat cheaper as well.
A used hub has got to be very cheap. If they have a european car interchange manual I suspect the old 114 and 115s might be identical too. Check the interchange manual if 123 types are not common in the yards near you. At least the spindal got no damage from bearing issues so its pretty easy sledding.
