second gen door panels in first gen with vent windows
 

I have a 1987 Ranger Super Cab that I am trying to swap in the door panels out of a 89 ranger. I already have the inside handle and the armrest bracket in. What do I have to do to get the top of the door panel in place? I removed the felt from the door panel as the felt is already on my door. I also have the vent windows and want to keep them.
