Yep, I agree Jeff. I think what I am trying to say here (and maybe it didnt come across right) is that these seals were designed to be on certain cars....and if you have a car that has the holes that show signs of the screws being installed then you are missing the seal. I have seen several cars now where we look at them and clearly you can see the seal was installed at one point.
However, if the door has no holes on the bottom I would not add the seal to the car.
I can play around with the wording if that point is confusing.
