V8 vs V6 Gas Pedal

The gas pedals are the same, the cables are different lengths on 67 and newer A-Bodies.
V6?
They never factory installed one in an A-Body.
The SLANT 6 and V8 cable/pedal assembly are a direct bolt in/bolt out affair.
I would get a whole assembly and just change it out.
Trivia......a slant 6 cable was used in 440 6 pack B&E-Bodies because it was longer and it reached the carbs.
