Mike,
Thanks for your interest in Airflows. 2 door Airflows are pretty rare. That is because the Airflow was intended more for a 4 door body. Chrysler hoped to use the Airflow across the lineup and the four door models were more practical.
So, the few 2 door models left are probably in private Airflow Club hands. I have not seen a two door Airflow except on the Airflow Club website.
I have not seen one on ebay, but I don't check all the time. The few "project" Airflows requiring full restorations I know of for sale - are four door models.
So - try to make headways through the Airflow Club. The officers will know of any 2 door models out there, in the club. Prying these cars away from the members will require wads of cash I think, but you never know....
