I made moulds from air dry clay. You need an original switch plate, on the inside of the switch plate put down plastic wrap and then start packing in the clay. Let dry a few days and then pull your mould out of the switch plate. It takes a good week for the air dry clay to fully dry like a rock. I then coated the dry clay mould with cookin oil and start laying the soaked fiberglass cloth, let dry, scuff it up and repeat with another soaked fiberglass cloth. After it dries pull out the mould. If your lucky it may come out. If not you have to break mould to get it off the fiberglass. After that get a dremel with a cutting wheel and cut off the excess fiberglass hanging down the sides,sand smooth and finish outside with some plastic filler. A real PITA , I made four for some of the bikes i needed them for. Never again:no:
