First off the white car is a completly made up car. The Ram Air was hand made from the owner in his garage. The pics of the parts of the Ram Air are some old pieces & some new pieces. The upper & lower new foam parts showing came from my collection that I sold to the now owner about 4 years ago. I bought them when I worked in a Pontiac parts dept. back in th 80's. Also all of the cars you see here were made up cars. none of them came from the factory that way. The only one you might be able to streach a bit & say it came from the factory that way is Tom Goades G/A wagon. It was a test mule that he bought from the factory while he worked for Pontiac a couple of years after it was made & put back to a reg. Le Mans wagon. He installed the G/A front end parts after he bought the car . The Ram Air & the interior parts of the G/A along with the Ram Air partswere left on the car. So that is the closest on that you can say came from the factory that way. All the others were converted into the Ram Air cars during their ownership. As far as the number of cars that were converted into Ram Air cars is really unknown , becasue there was lots of parts sold over the counter at the dealerships. I personally bought lots of the available parts when I work at the dealer.I know of 2 in my arae alone that were here back in the 70-80's. There has been a new want for the parts for the Ram Air for the 73's but as of yet no one has put up the money or the time to design one & repop the parts for it yet. maybe one day they will be out there but don't hold your breath.
