turbolag

hi the this is my first post i just picked up a used 2001 kingquad 300f great little rig unfortunately the front right cv axle is a little bent so it needs replacing and all the part sites ive looked at ask if it is an X z or a k1/k2 so im wondering how i find that out? also do you recomend any place that will stock that part and ship to the west coast of canada any help would be great thanks.
