Sorry I can't be more help with Stephen717's search for 1971 Tarrytown trucks, but here is a little.
1T617829 which was my old truck.
The only reason I know the VIN is because of my insurance company messing up. When I replace my 1971 truck with my 1970 truck, they never updated the VIN on my policy. My 1971 was sent to the scrap yard around 1993ish, but if you look at my policy it says 2010, with a year of 1970, but a VIN of a 1971 truck, so yes it took me about 17 years before realizing the issue. Good thing I never got into an accident with my 1970! Insurance companies go by VIN not the Plate.
Here are a couple of pics of the old girl and insurance card to build the total number of trucks produced from Tarrytown in 1971.
