Jim, The door seals (called windlace) on our older trucks goes on the cab not the door. The windlace goes under the sheetmetal trim around the door jam.

This stuff looks like a rubber tube with a flap along the length. The flap goes under the trim pieces and is all screwed to the cab. The piece for the bottom of the door is similar but it is kind of "U" shaped. You just catch one leg of the "U" under the trim.

I hope this helps.
