For anyone that doesn't already know, you can have your Pontiac vehicle verified through PHS (Pontiac Historic Services) for a small fee. They have the records on most Pontiacs and all you need is to give them the VIN and the fee and if the car is in their database you will get paperwork showing all the options the car had. Their website is:

For vehicles sold in Canda you can contact GM of Canada Vintage Vehicle Services if you think the car was originally delivered to Canada and sold their. My 70 SS396 L78 car has GM of Canada documentation which lists every option that came on the car. There is a small fee but if the car you ask about was never sold there and not in their records then there is no fee. Their website is:

And don't forget, that starting in 1972 GM finally had the engine coded into the VIN so proving things got a little easier from that point forward.
