The Crack of Doom can have a number of causes, principle among them in my
opinion being a design weakness and poor screen to 1/4-light adjustment.
There were two factory mods to the door skin I'm aware of, the first
appeared in *1963*, so the problem must really have been serious to appear
that quickly. This certainly improved things a lot, but as we know it still
happens after many years. I have see a further modification on Heritage
doors, when this was put into place I don't know. Before I saw the Heritage
mod I did something very similar to my door, and together with adjustment
has done the trick over the past 15 years and 40k miles. Full story at
