Day 3, put some new foam back up on the ceiling of the 1600. All seemed to fit pretty well and looks pretty nice.  Spent a loooooong time scraping and trying to remove as much of the nasty old windshield gaskets.  Got it as clean as I could.  Put the 1 cable tie mount in the back and am going to make my first attempt at installing the headliner tommorow. 😳
