Gauges

	The stock Roadster oil pressure sender (right) supposedly has the same thread (1/8" BSPT) as the stock Miata oil pressure sender. As I screwed the Miata sender in, I'm convinced the threads were crossing, but it's firmly in there and does not seem to leak, so I'm not touching it.
	I've jury-rigged the Miata tachometer into the Datsun. The engine idles pretty smoothly at 750 RPM, now. The air intake, with no filter, is really loud, as the video to the left demonstrates. The temperature holds steady at 180F. The thermostat and cooling fan are working.
