Dixco Mopar Hustle Stuff hood mounted tach

Sure ive had 4 of these hood tachs 2 original used in mint comdition and 2 N.O.S so i know what the difference's are . The later tach's like yours have a large Black plastic mounting nut and Black phillips anti spin screws. The red line pointer dial has a different shape and knurling to it. Also reproduction's had the Pentastar logo on the face plate as they could not use the Blue a Whit Chrysler Parts silk screen for copy right law's. I have a complete N.O.S " Hustle Stuff " " Chrysler Parts " hood tach now.
