Looking up production...

Where do you get the number of cars that were painted That color? 2804 in top banana. It has always been to my knowledge that Chrysler Corp. never kept records of that sort. They did keep a percentage of colors painted for models of cars like xx percent of all Dusters and Valiants were painted a certain color. The best you can do is engine, transmission, and the number run about half give or take a few. If 24,817 is the official number then somewhere around 12,400 were four speeds give or take a few hundred.
I have some breakdown of earlier models of cars that give 4 speed/ autos built but have never seen them for your model. I am unaware of there existence if they are out there. Would love too know your sources for this info. I would imagine there is alot of people who would like too see this info.
This salesman's guide give you an idea of paint for 72 by percentage of all Dusters and Valiants built that year
