E-bay should have one for you. All '03-'10 XB and 1125 wheels are the same except the 2010 Uly 3-bearing rear wheels.
As far as taking out the outer race only, it's not too big a PITA. The only way I could get the right angle on a front wheel was with a thin (SHARP) punch was to go through the little holes in the wheel hub, use a rag so you don't scratch it up and work your way around evenly.
Good luck! Don't wheels rotate the opposite way down under?
