I've been using magnetic trays to hold the screws, parts, and tools. Had more than one case of magnetized screwdrivers and grabbing a wrench and having the magnetic tray come with it. My wife bought me something called Grypmats to use on the Spyder. They're handy as they're flexible enough to drape over a fender or frunk without scratching. Some of the Grypmats have compartments to hold small parts or tools. Sure beats my magnetic trays!
