You can look at the driver's door where there is a tag attached to the door with rivets. This is called a warranty plate. It lists VIN and info regarding said truck.
DSO = District Sales Order. If the DSO is 71 or 72, it was sold new in CA therefore were required to be equipped with California emissions. It's different than Federal
trucks with lesser
smog equipment.
I'm asking because I may have the exact vacuum diagram straight from factory.
DO YOU HAVE THIS DIAGRAM?
