I had windshield in the way when removing/installing wood. I had dash padding in place when removing and installing the wood.
Driver's side more difficult when fitting wood. Trying to pull down wood with screws may result in screws departing from wood. I made sure the plastic nuts go easily on the screws - it is a hard to reach area and they have to go on the screws easily when you have your hand up there. Alignment of wood bows was also tricky, do not forget the small pad that goes between the two bows.
