Just installed my drop in idiot light tacho from "Rocketman's Classic Cougar Innovations" and I've got to say it's the ducks guts (Australian expression meaning awesome!).
Looks totally natural installed and the three wire hook-up was very simple. There is the very slightest mismatch in the white graphic between the new tacho face and the speedo face, but that's only because the speedo has faded over 40 years. The new black face on the tacho matches the black on the speedo almost perfectly. Also the tacho pointer is wider than the speedo pointer, but that's pretty unnoticeable too. Only problem I had was that when I took the car out on the road to test the tacho out it started raining and I had only washed the car yesterday....
