You keep asking about crankset, but any crankset that uses a square taper BB can be made to work, as square taper BBs have different axle widths.
You could swap your sugino 75 DDs for normal 75s that run a square taper, then make sure the BB you buy is wide enough.
EDIT - Seen your response. You can use any width BB. Thats why everyone is recommending them :/
indeed :/ just a minute ago I asked if anyone is willing to swap :))
The back of the crank bolt is meant to settle inside. That's why they are knurled. You gotta tighten them.
