The rectangular foil coil stickers were used on the late 250 GTEs and Lussos from 1963 on through the 275s, 330s, 365 single-cam cars and even the early Daytonas and c4s. The stickers were positioned 1/4″ from the bottom of the can in line with the center of the resisters. I have seen rectangular stickers that looked like they were printed on gold foil. These may have been an earlier reproduction, or may have been discolored due to the oily vapors and engine heat or may have been originals. Rectangular Magneti Marelli coil Stickers.
