hi folks, i noticed that my driver's door stop was broken and took it out. the little frame has a curved base with several concavities where the rolling pin rests, corresponding to different positions in which the door will stop. fine. looking on ebay i only see stop mechanisms that have a flat base, i.e., no stops.

in the absence of part numbers, are both styles original? are they for different doors of the car? does the difference matter?
