Speed-minder
Short answer: The Speed-minder was an option, and the tach was not part of it — no first-gen F-body had a tach in the dash cluster (that’s what the hood tach was for; Rally gauges gave water temp and oil pressure only).
Year tells: 1967 used a 120 MPH speedo (black face, chrome ring); 1968–69 used a 160 MPH speedo, and 1968 changed to a greenish-gray face with off-white lettering. So a 160 speedo with that face is a 1968 Speed-minder setup.
