I know this is an old subject, but I still have a basic question that is not directly addressed in any of the older threads that I found. Is it possible to remove the louvers on the top side of the deck lid without having to also remove the mesh and frame on the underside? I've got all the rivets drilled out on the top, but the louvers won't pop off. It looks like they might be riveted from underneath as well. Car is an 89 328.
