Ok so I was detailing the car and went to clean the hatch glass and the glass popped out. Is it glued in or a channel type? I didn't want to mess with it to much in fear of Breaking it.

 

I would presume that the glass is bonded to the metal hatch frame with adhesive like the windshield glass since the glass is part of the hatch structure. The rubber trim that surrounds the glass is cosmetic.

On the section that popped out, do you see any signs of adhesive? If you have any doubts, I suggest taking the car to a place that handles auto glass.

 

The hatch glass comes out relatively easy on these old cars, I've removed them more than one. If you don't already have a TII, I have the glass with the wiper hole and all hardware including rear squirter pump and tank, if you're interested. It also has good defrost wires.

 

It does look like there was adhesive but I also noticed that the driver side mount stud that is glued to the glass detached from the glass also.
