Just installed the pedals. I got a pair of the 3rd party ones, not the Mopar brand, and they seem to be the same. (At least for me) Both pedals were a little hard to go on at first but with enough patience they fit perfect. Here are some of my tips for installation.
Gas pedal: Obviously put it on from left to right as the right side clips snap on. I actually had trouble getting them to snap at first but then I noticed that since the pedal was pretty much a snug fit, the left side needed to be pushed in ALL THE WAY before trying to snap in the left. There shouldn't be any wiggle room.
Brake Pedal: After reading about how terrible it was going to be I guess I managed my expectations and prepared a bit. First I took notice of how the stock brake cover came off. I removed it from the bottom first and then upwards. So knowing this, the plan was to install the new one top down. I also used my front facing camera as a guide to see what the heck I was doing which really helped. It takes some time and you might have to restart the process again once or twice but all I did was guide the rubber with my fingers around the pedal little by little and slowly but surely it was completely on.
