This is some excellent information.
I guessing the newer sensors are more accurate because of the required computer inputs are unlikely to put up with the +- 10% of the old analog stuff.
Purchasing the sensor is the easy part. Finding the proper pigtail may be a bear.

I got tired of looking at the faded red when all the other gauges were bright. So I ordered an NOS temp gauge through eBay.
It arrived today. It was under $60 delivered. It came with the resister in a separate envelope.
They are reproduced but the cost was only slightly less and sometimes more than the NOS part.
Some of the reproductions had AC and MADE IN USA ON THEM. Some did not.
I also included pictured a re-pop with out the identification and the gauge black background looks to flat to me.
I was also suspicious when both gauges a read differently disconnected.

I used an adapter to connect my sensor to the LS motor. I was concerned it would not read correctly but it works great.
Cheers
