Very good chance.

A: The Hood Tach first became available sometime in Feb/Mar of 1967 on all Pontiac Models. The first style was the “TALL” style which refers to the height of the case. Also, the first style used only a single light bulb and there were variations with the face colors and redlines depending on carline and engine.

1967 Firebird (and very early 1968 Firebirds) used the Tall Style. Face background was Black with Green characters while the GTO and Full-Size had Steel Blue Backgrounds with White characters. After supplies of the ‘Tall’ Style Hood Tach were exhausted, the 2nd style came into production. This was a ‘shorter’ case (by an inch or so) and now had (2) bulbs instead of the previous (1). This new style was released into production on April 20th 1967 (even though early 1968 Firebirds continued using the Tall Style). The face on this first ‘short’ style was of a circular pattern. On June 29th 1967, this face was changed to an ‘oval’ pattern.
