I just went to install Rubicon rock rails that I got from a guy on my X and found that I am missing the hardware (except for the small nuts that hold the rails on the body).

Finding a nut/bolt combo for the 4 front holes should be easy enough, but can anyone tell me what the correct thread size is for the rear holes??

 

The Mopar instal sheet lists the bolts as 10mm and 13 mm socket sizes for the two types of bolts involved.(Dont over tighten) Torque settings listed as 8ft lbs(11Nm) for the smaller bolts and 16 ft lb(22 Nm) for the larger.
