Joe, some additional photos from a different car ..... installed, likely factory install, with the same orientation as the earlier one. The perspective on these is from the passenger side door, about a foot from the bottom .... note that the flat piece goes "down" to the door ... not pointing "out" or "in" relative to the door. The smaller portion of the "V" in the gasket to the door skin (outer) side .... the larger portion of the "V" to the interior of the car.
Hope these help more than they confuse.
The last one is held oriented to the door ... just like it came off .... with the taller portion of the "V" to the interior of the car.
John
