Speedometer

Thank you.
 
Bill,

I'll have time to reconnect the new Sigma Speedo tomorrow and will take a pic of the new unit and where it's mounted and then you can get a look first hand. Yes I still use the Analog Speedo at night as it is lighted but it bounces all over the place at times and is not very accurate. Some days are better than others but the digital always works, well as long as there is a battery in it.
 
Earlier I posted links to the Smiths/Caerbont programmable tachs. Did you not find the information you wanted in those links? There is nothing unique about a modern Smiths programmable speedo compared to an AutoMeter or VDO. They are all designed to accept pulses from 2-wire and 3-wire sensors. They all have programming modes that let you fine tune the accuracy to match your car's combination of tire size and final drive ratio. The biggest issue is not fitting or programming the gauge, it is sourcing a pickup that will screw onto the gearbox speedo cable point OR bonding magnets on a driveshaft to use a magnetic pickup.
 
I do not know where rivergate gets their angle drive adapters, but I do know that the output on them matches a standard GM speedo cable.
This is what I have on my Sprite.
 
Spedo bounces. You have lubed the cable I suppose.
