I have a 2006 sportsman 500 x2 that needs a new/used transmission. I can not find a replacement for my quad. I have come close but i am not sure if a part number model 1332367/1332533 can be fitted with a part model 1332624 from a 2008 polaris quad? If there is a difference what is it? All so could i just swap some internal parts from my 2006 to make it work?
