Maybe you can give me more details on what he hasactually done.
Thanks a lot. Still have time to do experiments b4 tonight's club race. 
You have to grind down the hub slots so that the nut slides down further. Also, do not use AE diff rings. You can use everything but the diff rings. The AE diff rings are thinner which causes the diff to bind.
