The very earliest Daytonas continued to use the red coils with the silver foil rectangular Magneti Marelli stickers. Later cars used the gold cadmium-plated steel cans and this blue/gold foil sticker. This one is from the Gold Daytona Spider #14383, one of the most original and complete cars in the world. During the production of the Daytonas the Fiat’s involvement in the production cars resulted in a lot of changes as did the new safety and emissions regulations imposed by the European countries and the U.S. government. The Daytona Registry www.daytonaregistry.com is the best information available to document these changes. Blue/Gold Daytona coil sticker.
