It certainly helps to jack up the front. The left and right end pieces are held on with about 4 hex-head screws (easy to remove) and two expansion rivets. The expansion rivets are in a slight recess, one a little deeper than the other as I recall. They are a bit of a pain to remove but if you carefully grab the insert with a beefy pair of needle nose pliars and rotate back and forth while pulling gently, they will pop out. Then the rivet body pulls out. The larger center piece I'm not sure about but I think I saw a couple of hex-head bolts from up top of the engine bay, looking down. Once you get the side pieces off I'mm sure it will get obvious for the middle piece. BTW, the end pieces are also attached to the plastic wheel-well liners which sometimes also get damaged. These are an easy DIY replacement (with the wheel removed of course). People I've heard having problems installing the JTD panel usually do because of some damage that affected the holes/mount points. A little ingenuity usuaally solves that problem. Either solution (stock or JTD) requires actively checking tightness of the h/w on a semi-regular basis. That's why they fly off at high speeds - because the h/w loosened to a point that strong air did the rest of the loosening ... and the rest is well-documented history.
Hope that helps a bit.
