Well there's this that applies to the older classic, but could probably be adapted to yours as well.
My gauges read a bit low though, but not far off what I see other cars doing. My Hornet, with stock regulator in the water temp gauge, reads low too. (Full-to-the-top gas tank rarely reads more than 7/8ths, etc).

Does anyone know where to find the diagram that shows how to convert the gauge cluster voltage regulator to the solid state system. Many years ago I saw it online and printed it but I can no longer find it. Your help is greatly appreciated in advance. I have a '69 AMX that the temp and fuel gauges read half of what they should. Any other suggestion would be appreciated as well.
