Re: MOPAR Gas pedal cover install
For the brake pedal, I heated it up with a hair dryer to make it pliable - got top and right side on easily - used a wide blade stubby screwdriver to reach behind, over the metal, and lifted small sections of the edge at a time - took about 5 minutes and no skinned knuckles. Do not use soapy water or WD-40 as others have suggested. It just makes a big mess and the pedal slippery, because you are going to need a good grip and I don't see any way around using the screwdriver.
For the gas pedal, I got the "hooks" over the right pedal side - made sure the top and bottom were aligned (it's actually a pretty tight fit) - lined up the tabs on the left side - then used my foot to press the tabs into place while sitting in the drivers seat. Took quite an effort, but that "snap" when it clicked into place was very satisfying.
Hope I never have to take them off for replacement, as I do not think the gas pedal would come off again without the tabs breaking.
