That is one base Model J GP, other than the color I do Like it, No A/C in NH does not surprise me for the era. I do like the Dog Dish with trim rings on this car, possibley stock but seldom see that way. Usually someone not willing to pay more $$$ for wheels or even full wheel covers, would not spend the extra $ for the optional trim rings.
Also I am not an expert on GP wheel covers, but I do not think that Style Dog Dish is stock for Pontiacs newer than 1970, my 71 Catalina came with this style caps. As did my 73 Lemans Safari.
I was going to point out the engine is definitely not a '72 but I see the guy says it's a '67 engine. And I agree with Jeff, I don't think those hubcaps were available after 1969-1970 and I'm fairly certain not on a GP either.
