ok so where we stand as of now is this, am I right?:

The biggest concern, what size is the stock axle. If its 19mm we can move on to the next step, what if the stock size is 20mm, will that be close enough? what if its the other way, could the fork be machined?

Next step, the brake. If this hub is wider that the stock hub, it may not work b/c I may not be able to space it correctly to fit the brake. Finding the origin of this hub is probably a good idea. I'll try to get the measurements from the guy, hopefully before he sends it.

Right?
