Quick question, google didnt help me

Hey fellas, Just wondering if rear drive shaft out of a 06 sportsman 800 will work on my 08 800. No parts stores open on the weekend and bear season just opened a few days ago, and im a bear guide so i need my quad lol
And by any chance can someone share a link to how to swap drive shaft out? Do i have to pull the rear diff? I thought i read that somewhere a while back
