I don't find a report that separates '67 Column shifted Powerglide from Floor shifted.
That's because Chevrolet didn't keep this kind of record.
However, if you take all the D55 Console cars (129,477) and all the M11 Floor Shift cars (12,051) and remove these from the total 67 Camaro production (220,906), you get 79,378 cars that came with the standard column shift. Of course, there's no breakdown between automatics and manuals, but I can guarantee that there were more than 600!
