You should get a body panel tool from your local parts store.
The panel is mounted with about 8 to 12 spring clips.
Each clip looks like a squashed V that surrounds a flat plastic tab about 1/2" wide and 1/2" long.
The tabs are fragile. They will snap if you don't pull the panel straight out.
My rear panel broke off. I noticed that broken tabs all snapped at a specific point. Before I reassembled the panel, I reinforced ALL of the plastic tabs using silicone window cement. Then I slid the V shaped clips over the plastic tabs and pushed them into the metal slots.
At the bottom, on either side of the latch, I drilled a 5/32" hole and set a self-tapping metal screw. Without the screws, the panel would probably break loose again.
To prevent the panel from cracking I ran several beads of silicone glue on the inside of the panel. :ugh3:
