This is a tachometer off my 1973 Datsun 240Z. I am turning the car into a race car, so I have no need for the factory gauges anymore. This tack works perfectly fine and is also in excellent shape. There aren't any crack or chips in it and no missing parts. This tach is factory, so it will only work with regulated points ignition systems. It won't work properly with an electronic ignition without installing an aftermarket resistor. The tach should fit in any 1970-1973 Z dashboards, but I'm not positive on that. Fell free to message me on eBay or call me with any questions you might have. (714) 606-1229 and ask for Mike. Happy bidding!
The above is a quote out of a ebay auction. Currently I have a Monster Tacho installed in my 240Z. I have a electronic dizzy and have a coil that does not use a ballast resistor.
Do I have to install a resistor to make the original 240Z tacho work correctly?
Sorry I do not have clearer pics I will try and get some better pics later.
