At one point, maybe a decade ago, we were going to put together a judging book for each model that falls under the KFOC umbrella. I had written several pages on Willys Aeros and sent them off to the committee and then the thing just kinda wilted on the vine. I like the idea of the National Convention having rigorous standards and judged cars being voluntary. I like the idea of having a book of factory standards and dealer options.
About the HJ door locks: as long as there is a lock on the passenger side, there should be no points loss. If there is an additional lock on the driver's side, and if there was never a factory option for it, there should be a point loss. If it was a factory-authorized dealer-installed item, perhaps only a half a point should be lost.
Another example would be the two-toning of a Henry J. There is a factory bulletin showing the correct way to two-tone a Henry J at the dealership. Technically, NO HJ should be two-toned, but since the factory authorized the two-toning at the dealer, then there should be a half-point loss instead of full points off on any correctly two-toned HJ's. If the two-toning is not as the factory authorized it - full points off.
