Its been a while since i've checked the forums here so I did a search and found nothing about moving the stock skid plate back and up. I came up with the idea when i was washing the mud out of all the nooks and crannies under my FJ. I took a picture so that you can see what i am talking about.
This pic shows that there are several inches lost behind the stock skidplate. By making a new top bracket (the one shown in the picture) and moving the holes on the bottom 2 bolts forward on the plate a couple inches, I should be able to almost have the tow hooks sticking through the skid plate holes.
If somebody has already done this please let me know how it has worked out.
