I just bought a set or pilot sportline pedal pads to put I my standard 2003 Ford F-150. They don't look like they will fit but I have to cut them open to tell. Me only fear is that if I cut them open and they don't work then I can't return them. So do you guys think they will fit? If so do I pull the olds ones off or leave them on and the gas pedal is plastic and perimently hooked so will the after market has pedal cover hook on top of that one ?
