[oletrucks] Truck serial numbers

[Kelly Watkinson <KWatkinson@creo.com>]

Does anyone know what the number AA972520 should be? It is registered as a
48 1/2 ton but it sure looks like a 51 to me. I checked a site at
http://www.chevytrucks.org/users/rusty1/numbers.htm but I can not find
anything starting whit AA. Any help would be appreciated.
