With the pedal in position, use the supplied bolt to secure it to the pedal support. Note that the new pedal attaches to a different hole higher up on the pedal support. Master Power's instructions note the positioning hole in the top of the support toward the front of the car; they say that most cars have this 3/8-inch diameter hole. If the hole isn't there, it will need to be drilled, which is easy to do because there's an indent where the hole needs to be. Our car's pedal support already had the hole in place.
