No idea on date but cool photo.
Let me guess.
2 RAII cars - one auto, one stick. The 4sp guy was making fun of the automatic guy. They race for pinks. The automatic was bought new and prepped at Knafels but the 4sp guy did not know. By 500 ft. the automatic already has a car length on him and never has to look back. They are in front of the county DMV so the 4sp guy can sign over the title to the automatic guy.
See how close they are. The 4sp car was in the back. For a second he thought about just ramming the automatic due to anger, but then a cooler head prevailed. He could not intentionally wreck a 68 GTO even though he just lost it.
(It is my guess; I can make it any scenario I want

)
