Install headliner
I ws dreading mine, and i'm happy with the way mine turned out. it's the only one i've ever done, and the only thing i'm unhappy with is my stretching job at the bottom sides of the rear window. i was getting tired and my fingers hurt by the time I got there, so i just did my best instead of being patient and waiting for another day.
I also found that to replace the cardboard panels in the sail panel area, the 3/16" (roughly) thick foam craft board in the school supply section of Wal-Mart works marvelously well.
this is the only headliner pic i have....kinda crappy.
