Spent some time in dealer yesterday. By luck, they had a front wheel off a 2007 and a front wheel off a 2009 (09 same as 10 I'm being told) and I was able to lay this question to rest. Axle threads and axle nuts are differrent, as mentioned above, but has no effect on mounting 2010 wheel on 2007. Axle diameters (where bearings will ride) are ONLY .010 different. So, if you have the resource, all you need to do is grind or turn .010 off 2007 axle, get 2010 wheel (with 2010 factory bearings) and assemble together. Simple as that.
I have done no research on rotor and fitment, but I will be shortly as I have the 2010 wheel already, just waiting to get time to put on my 2007 street gllide.
