autometer gauge to cylinder head adapter I am converting the car to all autometer gauges and have run into a problem with the electric sending unit for the water temp. I appears as if the factory thread pitch for the original water temp sender in the head is machine thread with a gasket. The autometer stuff is all NPT. I do not see a adapter on autometers website. I know that I am not the first person to do this. Any help to resolve this would be great. Thanks ahead of time.

The adapter has VERY thin wall thickness due to the sizes it is converting.

I was very careful when I did mine but did it in the wrong order and it did snap off - luckily there was enough sticking out that I could get a hold on it to turn it out of the head - otherwise I would have been screwed.

those adapters are peices of crap. I broke a couple of them. I think you are better off using the plug above the starter. autometer sells an adapter for it.
