I'm working with a fab guy now to get mine to drop down. if you look closely there are notched on both sides behind the bumper. I plan on using those spots for the hinges for the fold down and latches from a xj. one thing i have to consider is the computer. seems like anyhting i do the the JK causes the computer to freak out.

 

Would be a great mod. I don't know if you would have the room with the bumper as it is. I have seen mods like this for TJs but the back gate had the room to perform the mod.

given time I am sure we will see this mod somewhere.
