Throttle Cable Conversion For Early A

In other words, since my 64 Dart Gt 225 Automatic, is a non air conditioner car, I need to find a new accelerator pedal from an AC car slant 6 or a V-8 car correct? Does anyone have any other thoughts? Or, other accelerator pedal options?
yup early abody v eight or slant six with ac, the later 67 and up pedals will not let you give full throttle it hits the floor tunnel. looks stupid too
