One way to reduce droughts and wind blown water is to buy some D shape neoprene with sticky backing and fix it to the inside edge of the side screens so it meets the bottom edge of the leather door capping. Then with some square section neoprene and some of the D shape make a block for each side to fix to the edge of the scuttle panel so when the door closes the side screen butts up against it. This works very well. I can take some pics if you would like.
Look at seals direct.com, the struff I'm talking about will cost about £10
