1974 260z. L26, E31 head, 4 speed manual
I have an early '74 260z with the 4 speed trans. I replaced all of my gauges with some SpeedHut gauges. The SpeedHut speedometer uses GPS to calculate MPH, so I have no need for the speedometer cable anymore. My question is: What do I do on the transmission side? When I pull the cable, is the pinion going to leak gear oil? Was thinking about just capping the end of the pinion with a nut, but I have no clue what size/pitch the thread is. Any ideas?
