Grills were easy, remove the rubber trim, take off six torx screws (25), reach in and squeeze clips from behind, snap new grills in.
Sport pedals were easy, as the rubber piece slips on giving easy guides for drilling. I used 11/64 for the pedals and 1/8 for the accelerator. Not as nice looking as some other pedals, but they do match the dead pedal so I went with them.
