it's done all the time with old stuff with no criminal intent
While the intent may not be there, with all the falsified vins on muscle cars, not to forget guys doing it on wrecked cars to resell them, these days, it's just not a good idea to do it that way. I know it may not really mean as much on these old trucks, but the law does not look at it that way. It could be a real problem if the truck ever gets resold and it pops up that particular serial number comes up as a scrapped vehicle.
