Google AAR car codes and you will get dozens of lists.

Does anyone know where I can find a comprehensive list of AAR car classification codes?  The Freight Cars book by MR lists the Box Car and Refrigerator car codes, but I cant find a list of the other types of classifications for Gons, Hoppers, Flat Cars, etc.
