It takes time but it's all pretty easy. The fan guard next to the hood latch comes off, as do all the fasteners for the belly covers and wheel well liners that engage the bumper skin. I didn't count all of 'em, but there are probably about 30, maybe more! Some of them are those plastic rivets and they're reuseable if you pop them the right way. You have to lift out the center of the head first and then grab the body. When you put it back on take a breather and make sure it's all lined up and snapped back in place, then start attaching!
If you don't have grass (I'm not talkin' weed, here!) to set the cover on you may want to have a blanket laid out to help prevent scratches.
