Help with 1300 front wheel swap

I've been trying to fit this wheel to my forks like mjg15 did on his GPZ550 build
www.kzrider.com/forum/11-projects/397729...l=component&type=raw
but not having much luck. mjg15 said he used a Concours axle. I tried that. It is too short and the O.D. is too small.
Then I thought about a bearing swap from the police rim I have. The O.D. of the bearings are smaller on the police rim.
I have been trying to contact mjg15 also, but without any luck. Anyone have any ideas????

Never mind.
I found a 17mm axle from a KZ1000C
