My father installed a store-bought left gas pedal attachment on his 1951 Pontiac. It's on my '66 convertible now. In the intervening years, I bought a second one and it's on my 65 sedan. Very logical, very convenient: outer pedals gas, inner pedal brake. -ron 65,66 PS: I'm still using the panoramic rearview mirror he bought for his 1941 Pontiac.
