Well, you are welcome to your opinion.

Chrysler often had to engineer things just because of idiots. Manufacturers still do today. To deny that is to deny reality. Although they have never achieved true 'idiot proof' status, they do try.

And I do not agree that our typical Mopar vacuum advance cans retard timing below the mechanical. You accuse me of oversimplifying this, but you are really making this much more complicated and difficult than it needs to be. In fact, you are down right confusing.

It is vacuum advance. Been around since the 50s. A tach, timing light, hand held vacuum pump and a little knowledge and you are good to go. Shouldn't be above most guy's pay grade. Unless they make it way more complicated than it really is.
