Unfortunately, judging by the pic they show on the Fuzion web site of that cabinet in the 342 garage I don't really see how you can make that work.
We have a Raptor with the 12' garage and added one of those small dorm fridges for beer in that same spot, it's only about 22" wide X 22" deep. To fit our RZR 4 800 I have to put the right front tire right up against the side of the fridge to get it to fit. There's no way for ours to fit in front of the fridge and still close the garage door and since it looks like that cabinet covers half the front wall I think that is going to be a problem.
One other thing to think about is the height of the lower rear bunk in relation to your cage. I have to pull ours in right in the middle then turn the front to the left some to miss the fridge. I can't load it to either side because of the lower bunk brackets will hit the cage. If you still have the factory cage you will be very close on fitting under there with the rear of the cage. Even though the rear tires sit lower than the front since they sit on the dovetail I have to air our rear tires down some to keep it from rubbing on the bunk.
Good luck with it!
