you can get the specs on both bikes front ends from the dealer parts counter, they should be able to tell you the indvidual specs on the axles bearing and spacers for each.
I had a front tire put on backwards by another shop, n didnt want to go through the hassle of dealing with them again ( the brake rotor was marked on each side with a sharpie, n they still got it wrong!) So i called a friend who was parts manager for advice, he looked the parts up n told me I could swap the spacers from side to side and put the wheel on backwards, because the bearings were the same. I was still leary so he gave me the specs. on the axle bearing, and spacers ( different for L&R) . You can also try dennis kirk, they have an exelent tech line and well wheels so......
