I received the aluminum riser for the brake pedal with the "Seal" floorboards. I had made a small modification previously when I managed to strip the thread over tightening the pedal when It came loose on a recent trip. All I did was drill through the pedal and inserted two tapered round head stainless steel screw and locking nuts. I decided not to order a new pedal and when I installed the higher riser I received left it the way I had it. Since the pedal no longer "meshes" with the original pedal mechanism, I feel this makes it more secure, and shoul dnot loosen up as mine originally did.
