Door Weatherstrip

I'm installing weatherstripping on my doors. I do not have any of the original wx stuff for this car, so I kinda making my best guess. I must be missing a component. The snake head portion of the rubber does not match any of the existing screw holes, nor does it form to the opening. Any help, or pic's of a complete installation would be a great help.
