1 x SE840. Our unique conversion to fit onto LATE Electronic ( Straight port ) drilled heads to bolt on the earlier XK150 mechanical / cable type XK150 Tachometer Drive Angle box for Earlier XK150 gauges. Basically a direct to head 3-hole fitting with adaption to the earlier 2-hole type fitting that sat on a seperate 5° rotated spacer plate.
It is a straight clockwise to clockwise drive rotation for Early XK150 Mechanical (Nemag) Tachometer Gauges ( chrome ring pointer).
