I'm not sure about this but I feel I should warn you of one possible problem. The spindle taper may be incorrect for those cranks.....It would be best to figure out what that BB was spec'ed for and go from there to find a suitable crankset. Sugino used both ISO and JIS tapers which will affect your final decision for suitable cranks....
Anyone have a Sutherlands handy?
This should help to confuse matters:
