I wouldn't think that it would be to hard. I think that it is behind the plastic on the hatch. Prob just a srew driver to get that off and maybe a few bolts and you are in business.
That being said I have no experience just thinking what else could be in the way, prob not much...

I miss the days that they made toys that could kill a kid.
there's plastic "rivets" that hold it into the hatch, pull on it a little bit to see where they are, and stick a screwdriver in there and pry em out... you'll probably break a couple of em so you'll probably need to pick up a pack at an auto parts store. they're pretty cheap though
