Randy,
apart from restorations I usually use a cable deal. That way is is a lot easier to get from the pedal to the throttle arm with just about any induction package. It also makes it easier to change things if the engine combo changes. Don't use the red jacketed Morse cables though as they are not flexible enough. I use the same stuff as the fuel cars, a gray jacketed deal with a spiral wound reinforcement. You can tie knots in them and they still work.
