Most of the RACE cars of this era were using the Jones/Motorola, Stahl or Moroso mechanical tach. These have a cable from the back of the tack into the dist. housing. Of course you had to have the dist. that was conpatable to the cable drive tach. The Sun Super tach that you are showing was the one to have for street cars but if you are going for the accurate race look, the mechanical cable drive one is the way to go.
