5911 x 1.  XK140 & XK150 Speedo Cable which is  57" long for fitting to the standard XK140 & XK150  'De Normanville Laycock', Overdrive Gearboxes. The cable fits the 3mm box drive from the speedo head  but at the other end  fixes onto a 90° angle drive conversion box (4836)  that is screwed onto the gearbox drive gear (also a 3mm box drive ). The cable does not then require a loop into the box as it screws into the angle gearbox, so is 3" shorter than the manual cable. Original Ref. Number C11964

For the angle drive box SEE :  4836  ( These are often used on other properly designed modern gearbox conversions into XKs ).

For non-overdrive gearboxes use cable : 5910

NOTE : This cable should also fit a Supra 5-speed conversion if it has the 4836 angle drive fitted.
