Transfer case absolutely BLOWN

So i bought a 2010 ranger rzr 800s from this dude a couple weeks ago and long story short it started clicking and i narrowed it down to the transfer case and took it all apart and not 1 drop of oil in it and it had mud in it so every bearing was shot and every gear was rounded teeth and shot and everything rusted so where in the hell (besides a polaris dealer) can i aquire a new set of gears bearings and seals and bearing shims
