perhaps the gaskets on yours were ok then. I know on mine they were dry, brittle and flat as a pancake. The new ones I fitted were about 5mm thick and then compressed to form a tight seal when refitted. The switches seemed pretty watertight too from the back around the electrical connectors. The gaskets aren't expensive either, I think I only paid 75p from the dealers. The hardest part was scraping off the old ones.
