Anything is correct for modified. To answer your question as specifically as I know how, electronic ignition did not debut from Chrysler until May of 1971. Also, the orange box, to my knowledge was never offered right from the factory. It was a Direct Connection/Mopar Performance piece. But as mentioned, it is an improvement over points, at least in the sense that you no longer have points to wear out. Plenty of racers have proven through the years that a point type ignition in good shape with a hot coil can run every bit as good as electronic ignition. The difference is normally, the electronic ignition does not wear out like points do.
