Dave the dentist in London ON had a 68 2+2 with a column shift auto transmission.  It had a console, with a blank plate where the shifter would go.   That's as close as I can come to an answer for your question.

While there were U.S. Pontiacs in the sixties that came with 3-speed floor shifts, the Canadian Pontiacs were like the full size Chevies in that they did not use a floor shift with any 3-speed. Cars like the Chevelle, Nova SS, Camaro SS did offer 3-speeds with floor shifts, just not the Big Car line. Basically a 3-speed 2+2 would have the column shift, then an automatic console with a filler plate that matched the rest of the console top plate trim. I have not seen a 68 - 70 2+2 blank console, but I have seen a 1964 Parisienne Custom Sport convertible with a 3-in-the-tree & console with filler plate (it was a very cool car).

Attached is a picture of a 1967 blank console from a 3-speed Impala SS. The same console would be used in a Canadian 1966 Parisienne Custom Sport & 1967 Canadian Pontiac 2+2. The picture is from an e-bay 67 Impala wagon that had buckets & console added from a 3-speed Impala SS, so don't get excited about it having only 2 pedals.

I had a black 1966 Grande Parisienne with a 283, 3 speed on the column and the console had a long slim ash tray where the automatic shifter would have been.

That would have been a really neat car!
