The earliest ones -- mid 70s -- were done in F. They switched to metric gauges (degrees C and bar oil pressure) very very VERY early in the production run. My best guess is that this was to save them having to build two different clusters in an already huge number of configurations. The font they printed the labels in changed at the same time, whenever the change was. The early early early ones were in some sort of all caps, if I remember right, and then they switched to bolder, more modern looking lettering -- and quit labeling the gauges. The "TANK" and "OIL" labels disappeared completely on all clusters from the late 70s, early 80s clean through until today. You just get degrees C symbol, a picture of an oil dripper, and a picture of a gas pump.
