Car is a 1972 cutlass supreme convertible, orig. engine was a 350 2-barrel, now has a 455 4-barrel. automatic trans. The gas pedal has 2 cables connected to it, one is broken. It drives with the one cable just fine. I traced the second cable (the broken one), it goes near the destributor, then I can't tell where it goes after it goes down behind the motor on the passenger side. What is this cable for and how can I fix it? It is broken right at the gas pedal. Thanks
