Voltage regulator dart rallye cluster?

Mike
I dont know about Dart Rallaye clusters, but the Barracuda/Duster Rallayes from 68 to 70(the ones Ive had apart)have a plug-in regulator. Its a little tin bisquit shaped thing about the size of a maxi-fuse. It plugs in towards the radio side and only operates the fuel and temp gauges. They can be converted to electronic and work flawlessly for many many years. Mines been going for 15 plus years now.Are the Dart Rallayes different? I know the standard non-Rallaye gauges are exactly as you say.
