I have Spina Bifida and it limits the sensation in and the movement of my right leg below the knee. 27years ago I bought this pedal that is bolted to the floor and allows me to run the gas pedal from the other side of the brake pedal with my left foot.
The techs at the dealership that I bought my FJ from, simply flipped some bolts upside down and welded them to the floor instead of drilling through the floor to screw it down. I was quite impressed since I usually just drill and bolt it down.
The pedal simply folds back when someone else needs to drive the truck. It is a very straight forward design and it's age is starting to show but it's utility is timeless.
