Headliner
I did mine myself and it turned out pretty good. I`d suggest laying it out for a week or more with weight on the folds. I regret not doing more insulating there on the roof but that`s water under the bridge. I used one clip per seam and several more at each end with lots of cement. Be patient and make sure you pull everything tight and you should end up with a nice job. I think the factory service manual had the play by play.
