I think if you drop the wheel well liner, you're going to get a good look at all the hardware connecting it to the frame and other body work. More than likely there will be alot of fasteners and probably some adjoining parts that need to come off in order to pull it.
I pulled my lower front fascia piece from below the bumper to Line-x it and it was full of fasteners and clips. Very tedious, but not impossible. I have a lot of tools, so that makes things easier. I know my Milwaukee electric ratchets were incredibly valuable.
Maybe wutang61 can give you some tips. He posted some good drawings for me. He knows a lot of good stuff about automotive work.
