On my current project I am redoning a 24 Challenger. It has a 460 with OMC, not my pick, but the hand I am dealt. I want to put on a Gaffrig style 2 handle shifter/throttle. Will the throttle/shift cable and safety switch mount up or is there some conversion needed?

i believe you will need to but a cable adapter kit . if not then you ll need 2 new 33c cables with the omc install for the engine side and use the hardware the throttles come with.
