I have the Mopar towbar for my 2010 KK.
I got it used and tried to fit it without success, the mounting holes do not line up. I dont know how the last owner managed to get it to fit.
Yes there is 3 bolt holes on each side of the towbar, the tow hook needs to be removed as that is one of the mounting hole.
I ended up drilling another hole in the towbar to make it fit.
The spare tyre WILL NOT fit after this towbar is installed, I will have to carry a half deflated spare tyre and air compressor with me when I need the spare.
