It's a 67 with a 98 5.9 magnum but was this way when I bought it. Have never had a problem with it. The ignition switch is the original and a bit loose but no more than others I've seen.
Have also done the MAD upgrade...
OK but you are not answering the important question. do you have the 67 style alternator or the isolated field (70/ later) with the flat electronic regulator? Or what else?
Cannot offer much help until we know what you have
