Designed to drop into the standard 3 3/8″ hole in your dash. White numbers on a Black Face. These are correct in that they are 0 – 25, and have the hour meter. A light kit is included. A side note: Famed CASE Instrument Restorer, Joe DeMaio said that the internal workings of this Tach, and the expensive “Genuine CASE Tach” are of the same origin, and identical.
