Why does anyone care. They made 13,000 of them, more or less. The only ones
that might be significant would be first produced, and last produced. They
were a mass produced vehicle, not quite like a Duesenberg or Ferrari where
only a handful were made, each unique from all the others. What is
important on GMC's is year model, to i.d. what equipment they might have
had when they left the factory. After that date, all bets are off.

78 GMC ROYALE 403, left the Michigan plant in May, 1978. Upfitted by Jimmy
Industries. Sold later that year to a broker at a Honda dealership,
original owner drove it to Long Beach, Washington, where he sold it and
flew home.
