68 Headliner Advice

[Kisner]

After removing my old headliner in my 68 coupe, I'm now 95% sure I'll try installing the new one myself instead of paying someone $75 to do it. Unless I'm missing something it appears after I glue in new insulation, the headliner itself is only held in by 4 long rods and then pulled tight and glued in around the 4 sides. My question is - is the headliner supposed to be glued to the insulation? My old one wasn't. Looks like the rods, once swivelled upright hold it tight, along with being glued behind the front and rear glass and sides.
