I'm going to install my first headliner 1965 Dart

Well, my first fabric one anyway. I've installed several in the many 72-76 Dusters and Dart Sports but they are solid fiberboard or reproduction plastic.
I've seen a couple of YouTube videos and figure that I'll give it a try. I'm looking for advice on a few things. Please forgive some of the following for being redundant or silly.
It has a headliner in there now but is ripped. I do plan to remove the windshield. It is cracked and I planned on replacing it anyway. Th car is a 2 door post model. It has no sail panel cardboard panels, just fabric. It has trim panels around the rear window that I guess hide the barbed areas that the headliner hooks into. Same with the panels below the quarter windows.
I'm unsure about the sides. I don't see where the fabric is attached there. I have the weatherstripping out. Is it glued up in there? If so, what specific glue is suggested?
I plan to open and unfold the entire headliner and let it sit in the sun to eliminate as many creases as I can. I have heard that some can be flattened out with a hair dryer or heat gun after installation.
I'd appreciate any suggestions! Part of the reason that I am trying this myself is that I have so little time through the week, I cannot take it anywhere. It is NOT registered either, that is on the list.IMG_2710.JPG IMG_4127.JPG IMG_4260.JPG IMG_4324.JPG
