OP message me if you can't find anything..., My wife had a stroke 17 yrs ago. Right side bad.. We retired in Thailand while back. She had a car in Houston fitted with left footed gas pedal, I sold car but kept the gas pedal. This is anodized aluminum stainless base/sub base stainless shaft, sealed bearings. Bolts to floorboard and plate covers the OEM gas pedal so bad leg/foot can't get to it.
Assembly pops out (10 seconds) so can be used normally by anyone else. I bought her a small Lexus in 2008 because..it had auto wipers, when it rains they come on, Keyless entry and auto headlights.. Also had the knob on steering wheel but thats on our current car and not going. The left foot gas pedal though is looking for a good home. Freedom Wheels in Houston TX did all sorts of crazy stuff, I saw quadriplegic in a custom 3/4 ton 4 x 4 van. He only had use of one hand and drove everywhere.
