Ryanz, Yes, because it rolled over after 10,000 trucks were built(for the USA market). Your truck was 10,539 to be assigned a vin number in 1971 at Oshawa for the American market. GMC's built at Oshawa for the Canadian market used the Chevrolet VIN format and used a 9 between the Chassis and Engine codes to denote GMC. They also used 100,001 as a starting number.
But because your truck was going to the USA, it uses the USA GMC format which has a starting number of 10,001. That's 10,001 with the first truck. So 20,539 - 10,000 is 10,539. Thanks for the kind words, Bruce
