Penske climbs the hill after Start/Finish on his way to a win at the Oct. 21, 1962 Pacific Grand Prix. 

The car was rebuilt from a wrecked Cooper F1 car.  It retained the formula car's central-seating position, which caused an uproar at the time.  It met the letter of the SCCA rules of the time, as did the earlier "Bobtail" Cooper, which also had central-seating for the driver.

The car later became the first of the racing McLarens.
