A sticker inside the glovebox door.
A sticker on the driver's side inner fender in the engine bay.

For example, my 1984 has it's SPID on the driver's side inner fender.

If you find it, look at the list of options, and they will have codes with letters and numbers. These are RPO (Regular Production Option) codes. It is possible to find a list of each of these codes online, as they apply to your truck.
Cool. I'm actually going to go pick the truck up next week, I'll check it out and see if it's still there. Thank ou.
Do you have the website where I can get another one if it's missing?
