Ok, for some reason, mopar only has one tow hook for the KK unless it came that way new. The KJ tow hooks are the same except that you get two for approximately the same price. DO NOT use the M bolt that comes with them. The bolt is about 5/16" diameter and goes to a curved point, terrible design. Instead, purchase the stud plates, remove the bumper fascia, remove the uniframe caps and install the hooks. The reason that the tow hooks pull through the uniframe is because it's about 5/16" thick and there all of the recovery force placed on a round bolt that comes to a point. The metal just can't handle it, not for very long anyway.
The replacement tow hooks for the KK are available but very expensive.
This should take you to the hardware kit. This kit along with a pair if KJ tow hooks will set you right up.
