SPID information.

[Rodk65]

I recently purchased a 1969 C-10 4x4, this is my first C-10 and I have been searching the site for information but have been unable to locate. The original SPID was removed by the previous owner during a repaint and was misplaced. I have been looking at a tread that has pictures of different SPID's and have noticed that all have a Model#. Where does this model# come from and is it listed anywhere else on the truck? I am considering having a new SPID created and would like to include as much accurate information as possible. Did they use a cowl tag on trucks like they did with Chevrolet cars?

I am also searching for information on the original colors that were available for my truck in 1969. Any information is appreciated. Thanks Rod
