There is a thread on the fender liners already, go search. I installed my liners I purchased from moparforless. Search will have #. Plastic rivets I got from bumper to bumper for a few bucks. They just pop in. You can reuse 1 that comes off with the small flap that is in there now. Took 10 minuts to do both and well worth it to keep all the road crap from underneath the fenders.
