'68 Dart Convertible Stuff

So I just got my car and I need some answers. My '68 convertible is missing the bottom windshield trim and I'm also wondering about availability of other trim pieces for this car. Also, the carpet around the center console is a separate piece, is it supposed to be like this? Additionally, I noticed that the drivers side window has a little hole in the upper right hand corner that is noticable if the window tilts a little towards the rear of the car and pulls away from the track's channel; I'm guessing that something hooks into the hole? Finally, is the rear snap-in piece (looks like vinyl) that separates the back seat from the trunk (I don't know the technical name) available from any of the Mopar parts people?
