I'm trying to install my weather striping for the back hatch, which I didn't remove. I see that there is a factory rectangle hole on one edge which I think is a drain hole,.. I think, of course I believe that goes on the top, also there is a factory paint mark on the weather strip, I think that goes on the bottom.,... I think. Yes I know the top of it is narrower than the top, at this point hard to tell. I should have posted pictures, and I will if I can't get an answer.
