trimmings
the first step is to remove all the ceiling fittings, the sun visors, the handles above the doors, all the interior lights and the holding screws behind the rear interior lights (best to disconnect the fittings and tuck the wires into the holes, well out the way), certain trimmings around the outside. these include, the top half of the two trimmings either side of the windscreen, and all the door rubbers.
