I'm kinda late to this conversation haha but I just stumbled across it while searching for Info about these "indy" trucks I might just know where a couple are located! From my understanding all of the trucks were Sequential vin numbers. After the race they went to a dealer auction in indy and were sold to dealerships, then were sold at thoes dealerships as used vehicles. Approximately 10 trucks received the indy decals only 8 were factory white 2 were not, due to ford production being behind, only 6 made it to the track, and the 2 that were not factory white were repainted to the factory colors and sold
