Bill,

My truck had the headliner material glued to the roof all the way back! There is still some left. It also has the same material glued to the sides between the ribs and behind the package wooden bars.
One I looked at in a junk yard was the same. I thought they all had it. Also, the one in the junkyard had a curved metal filler panel
that went all the way around at the top. It looked like the inside of the cab. Mine doesn't have that.
