For those that are looking for the "period-correct" looking tach in their FJ40's, we went with this model from Wild Horses 4x4:
Our '72 has a SBC and we needed a tach. It's an Autometer gauge with their custom face and needle installed. It should work with the factory F and 2F engines as well since there's a selector switch on the back of the gauge for 4/6/8 cylinder engines. Of all the offerings available, I think this one looks the best.
