65 Barracuda question

Tach could have been added. In 1965 is was only available on the "S", but any dealer could have added it. The hole looks factory. Dash could also have been swapped out. A lot of 273 2 barrel cars got a four barrel throughout the years. If the wheels are 5 x 4.5" pattern, the brakes have been changed. Disc brakes were available in 1965, but started as a dealer option and were factory installed at some point during the model year. Very uncommon, even on a '65 "S".
