Haven't even owned this thing a month, let my idiot friend take it out and he rolled it.  Snapped the passenger side rear axle, and screwed up the front passenger wheel. 

I can't find parts for this thing anywhere, and I don't want to go to the dealer for them to overcharge me.  Will parts from the Zforce 800 and/or Uforce 500 fit as an OEM replacement?

Doubt it. Go to Alpha-Sports.com and look-up the parts you need. Sorry to hear about your new machine. Happens more then it should.
