Here is the correct one.

Others have purchased a good one from Lectric Limited, and the size and shape is exactly the same as the one I picture from Amazon.

There is no 3/8" NPT sender that works with the gauge, and you can only use the 1/2" NPT sender with stock gauges.

If you want to put it in a 3/8" NPT hole you need to have it turned down and re-threaded by a machinist. Forum member A1971Blazer turned mine and threaded it, and others have reported forum member brian mac does the work, too.

You instrument cluster looks like a stock one, but Accelo asks a good question, does the temperature gauge on that cluster come with an specifications or is it sold as a direct replacement for stock? Or is it a restored stock cluster?

Thanks, the cluster is a direct replacement for stock. The adapter looks to have an 11/16th thread diameter and 18 pitch on the threads. The sending unit that 2as in the adapter looks to have a 5/8th diameter and 20 thread pitch. Thanks for your help on this. I looked for size and pitch on the unit you linked to on Amazon but don't see that info. Do you happen to know if it fits my engine or maybe fits my adapter?
