My understanding is that the stock temp gauge is proprietary and works using an electromechanical process. It has a small set of contact points that open and close sending a signal to the gauge. I don't think it would be synchronized to work with the modern gauges available today. Most of the mechanical temp gauges currently available use a capillary tube filled with ether and are calibrated to work the gauge through expansion and contraction of the gas in the tube. Electrically operated gauges would need to use the sender that comes with them and wouldn't work with the stock gauge.

Give us some feedback if you have any success to the contrary.
