The black box in the '72 H/O was the digital tach that came out in '73 and' 74. Remember when digital was the single red lines and not the black LCD's!!! Sunroof car-- one of about 300 if my memory serves correct.
While on Olds, the '70 'vert 4 speed had my heart pumping!!! One of my first Olds friend had a '70 w-30 Rallye Red with black stripes. It was originally a 4 speed bench and he made it into a 4-speed, bucket with console. That amount of torque with a 4-speed and gears!!! Insane!
Sorry, back to the bow-ties!!
