What are trying to acheive? I'll bet DK hubs will be uber $$. I believe 400ex hubs also fit Blaster/Banshee axle. What would have to be modded on hubs to work? Maybe mod wheels? Maybe sell and buy what works straight-up?
I have a set of Blaster wheels a machinist re-drilled for 115 and gave me spacers to clear little ears on hubs. Tho I might notch wheels instead.
