My father-in-law helped me install these at his auto body shop last summer.
On the sides, we had to drill the holes. We first pre-drilled a hole using another piece of metal to make sure the drill hole was the perfect size for the nutserts. Then we attached the rocker panels on the bottom (using the pre-drilled holes), took a metal punch and punched a point for the drill holes along the side. Then removed the rocker panel, drilled the side holes, and painted the holes with primer. Then we inserted the nutserts with a sealent. There was a special screw that you screw in that tightens the nutsert (and they were tight!). Then you remove the special screw, put the rocker panel back on, then put the screws in that stay in for good. Something like that!
As far as the screws and nutserts, Mopar did a fabulous job
and just threw them loose in the box along with the rocker panels! The box broke open in transport, so half the hardware was missing. My father-in-law contacted a buddy at a dealer, who got us replacement hardware at no cost (yeah, I know their expensive to buy on their own!). Plus since the hardware was loose, it scratched up the rockers, so we ended up taping them off and repainted them.
They look great btw. I wheeled in CO right after the install on some rocky trails around Ouray, and they didn't get any scratches. Funny thing is that I actually got some scratches right above them, below the door frame.
I have Rubi flares going on as soon as it warms up.
