Change was in 75. I think it will work, but the color of the face numbers etc. are a little different. I actually put a `75 in my 66. But that required some serious fitting.

I replaced the original tach in my '73 with an electric from a '76 and it fit right in. Just had to wire it up and it'sworked fine since.

75 and 76 will work, but as stated before the numbers are white.

The tach will work just fine, it a shame but you can't do a face swap on tachometers. The electronic face has a tighter pattern than the machanical face. You could swap out the green face speedo for a white faced one to make them match.
