Doesn’t say anywhere that the truck has to run. Use the VIN off of the parts truck you drug home. If you ain’t cheating you ain’t trying. They for sure are not coming to your house to verify mileage.
I do have a friend who’s been registered for more than 4 years and he averages a freebie about every 3-4 months.
I registered my 59' this afternoon, just the VIN and a picture. I received an email shortly after saying they accepted my request.
