Considering the time I posted that I do not even remember who’s airplane it was... I’m sure it was a headliner installation that I did before glueing on the exterior fabric, which won’t help you in your current situation... I did do one recently on a Pacer that was already covered by a different mechanic though...
It is best to wrap the headliner into the window channel, it needs a good strong bond so when you use a steamer on the wool to shrink the headliner it won’t pull out and cause a bad wrinkle..
Bad picture... this aircraft has AirTex side panels... but this is the section behind the rear window, there is a piece of channel there that the headliner is normally retained by a strip of aluminum and #4 screws...here the screws are retaining the side panel instead..
The headliner is glued onto the top of the hat rack angles and the hat rack is put on top... I trimmed the sides of the rack so it goes on easier... this takes a lot of time to get right so that the material does not “bridge” the angle...
The rear is glued around the bottom of the channel...
View of it from the top... I will be installing the hat rack with #10 screwed with Nuts on the bottom...
The rear close out is the original .016 panel covered with scrap material and the door opening is treated like normal..
Whenever I install one of my skylight mods I always trim out the rear opening area with .016 panels and cover them with excess material...
Hope these help
