I followed the links and got the production plant, production year, model, and number off the line produced. But what i am missing and i am not sure if it is in the vin is what are all the finishes or is it left up to the factory to decide how many of each color get produced?

By the way both of my trucks were built in los angeles, ca one is a 1947 the other is a 1949 both 1/2 tons. Although the 1947 is a 3 window and the 1949 is a deluxe 5 window
