Re: 1996 Crown Vic Headliner removal?
Yes the above is correct. You may also have so ADHESIVE inside of it that is holding it to the roof. I had this with a 98 grand marquis. What I did after removing all the trimmings was to get a broom stick or long pipe and pick and pry easily at the glue and get the glue to unstick , then was the headache of puilling it out of the car thru the front door without actually brreaking. To replaced the old liner you peel it off, then get a wire brush and get as much of the old liner/foam and glue off the fiberglass . Then go buy some yellow spray glue (2 cans) and use that to install the new liner. Some cloths material stores carry the headliner material which already has a thin layer of foam on it. It somewhat of a job, but it looks good when you finish it. The liner material was about 12 bucks, the glue for each can was about 8 bucks.
Lay out the line and start at one end and move towards the other using the glue as you go. Try about 8 to 12 " at a time. You will have to trim to wrap to the underside of the fiberglass. good luck!
