Here's how I did mine :
Remove the rubber type trim piece, then all the screws from both sides. Unbolt the seat belt (2 large bolts, one at the top and one under the carpet, I cut a small hole and shoved the socket in). Remove the front and rear door aluminum trim pieces that sit at the bottom of the door openings (the ones that say AMERICAN MOTORS).
I think they hug the frame they are on a bit, so it might take a bit pf pulling. AMC was odd in that they liked to use 2 sided tape, or some nasty thick glue crap, to hold on random pieces of trim.
