2002 ford explorer spoiler removal?

So I have a 2002 ford explorer and it has a stupid freaking spoiler looking thing (I believe it's supposed to make air pass over the rear window to keep the window clear) on the top of the tailgate. So I'm just wondering if anyone would know (A) How to remove it? Or (B) where the heck to go to get it removed? I live in Salt Lake City Utah.

Is it on the glass? I've removed several explorer hatches and nothing rings a bell. If its hatch mounted swap hatches out, if its glass, swapp glass. Of course good luck finding a hatch where the plastic below the glass isn't cracked lol. I've prolly seen em and just don't really pay attention. The hardware on that glass is a p.i.a.
