Thanks for the SPID.
Very Nice!
To answer your question on the prefix and suffix numbers and letters. These were used mainly on early trucks to differentiate the specific option configuration a truck had. Generally they do not apply to most of the trucks on the board to any great extent and often not used thus the three character codes.
An example of this is on a 67 the chromed bumper rpo code (V37) did not indicate front or both, the suffix numbers did.
