What I did was take the throttle cable and pedal assembly out of any mid 70's chevy truck. After the engine was in, I mounted the cable and carb bracket to the engine and looped the cable in a nice loose loop back to the firewall. I then drilled the hole and used a file to make it square so the cable would stay clipped into the firewall. I attached the pedal assembly to the floor after a little bending and modifing, it was perfect.
Good luck,
Scott
