If the GP is anything like my '95 Cutlass Supreme, it's pretty easy to take off. No special tools needed, just screwdrivers. You'll need a flat blade screwdriver to pry off the little cups behind the door handles and Phillips screwdrivers for several more screws at various other spots. The screw that's often overlooked on the Cutlass Supreme is in the bottom of the door pocket. Someone overlooked it on mine and tore it up on the driver's side. I need to find a new one but the only one I've ever seen at a boneyard was similarly damaged. Also, be prepared and have a supply of the nylon fasteners that hold the panel in place because you'll definitely need to replace at least a few of them. Fortunately, they're pretty cheap.
