Thanks for the DIY. The gas pedal was so easy, done in under 5 minutes.
I spent 30 minutes on the brake pedal...gave up
Came back, soaked the back with vinyl conditioner. Slipped the bottom and left side on. Pulled hard and got the right side on. Then all I did was push on the top of the pedal itself very hard (the metal part), and the top part popped itself in place.
