How things have changed.
Note the lack of fencing...
Actually, the Ford had not broken down. It had a flat tyre. In those days, they were standard production cars and had to carry the spare, jack etc in the boot.
From memory, the Ford was leading with about 11 laps to go.
I like how the marshal just wanders down and they have a chat as the driver changes the wheel.
Right as to year and position....
