no.. the speedometers are correct. in 1968, the 150 MPH speedometer was part of the Ralley Cluster Group option which included the 150 MPH speedometer, trip meter and wood grain accent covering on the dash. in 1969, the wood grain dash cover came with the Delux Interior option. i believe the 150 MPH speedometer came standard with the 340 or 383 engine both years.
