Steve this is really getting confusing. If you are working on a 1954, 3100 then the rubber that goes around the door starts on the bottom 14" from the front pillar and is one continuous strip all the way around the door till it meets again at the bottom. There is a "Z" shaped channel with a reverse 180° rolled up edge that can be seen in this picture:

This runs the full length of the door opening and is held down on the corner by a "U" shaped channel. The channel that is in Alan’s second link is for pre-1950 trucks.
