The Classic Instruments cluster includes a 140-mph speedometer, 8,000-rpm tachometer, and gauges for fuel level, voltage, coolant temperature and oil pressure. The six-digit mechanical odometer reads 18,000 miles, which reflects mileage accrued since the completion of the restoration though the chassis’ true mileage is unknown.
