Couldn't have been many made with this powertrain (if it's original)

Imagine if the documents came back with 409 on them........

The car looks great, but the pictures don't do it justice.

All of the Custom Sport items appear to be present. Car may have been repainted as I don't see a dealers emblem.
A pic of the data plate would atleast let us know the scheduled manufacturing date and whether the 4 gear was there from the factory.

Yes, lot's of mid-year changes to U.S Chevrolets: 396 was big news, TH400, 283-220 came back in the U.S. the intro of the h.d. 3-speeds. Mag Style Wheel Covers came out mid-year.

Meanwhile in Canada things just kept on as they were with the Chevrolets & Pontiacs. There was no need to re-issue all the manuals mid-year. I think the latest car built that efforts here have uncovered were that April was the latest documented 409 car example found. Meanwhile 4-speeds were all Muncies & humble 327s came with 12-bolt rears in '65. It would not be a bad swap to drop in a big block like it was born there.

I asked the seller about the engine. His reply:
Everything but the motor is original. They didn't come with 396 motor but it may have been a special order

And the cool part was us getting 12 bolts in cars with as little as 283's and 3 on the tree or Powerglides. When I tell US guys that, they just shake their heads and don't believe it, or wonder out loud why Canadian Pontiacs were built that way.

As Vince states above there are even 6 cylinder cars with them.

 I would say that all of my 6-cyl cars had them. Back in '88 when I moved to Labrador, those cars were mostly 6cyls. The frame and 3:36 diff from a donor 4-door '67 Strato are in my Rag. A '70 4-dr sedan Parisienne that I converted to a 4-gear was a 12 bolt. My 2-dr h/top Parisienne was a 12 and the 12 bolt posi I put in it was out of a '69 Parisienne 4-dr sedan. The '66 and '67 4-dr sedan Strato's I have here are 12's. The odd duck is the Labrador '67 G/Parisienne bought originally out of Nova Scotia with a 327/Glide was a 10 bolt. That blew up, 12 in there now. And I have a '70 2+2 here with a 10 bolt posi. Odd...

An extreme common occurrence in my travels for me.

Seller emailed me this morning stating that the previous owner said the car is 1 of 250 with whatever powertrain combo it originally came with.

 We need that documentation, as already said imagine if it were a 409, or maybe a 4 speed 327 300 HP car. UGH!
