1) I was told that a flywheel from an externally balanced 454 would work on a 400. true or false? what year(s)454? 2) are the rivets on the vin tag specific to auto manufactuers? I'm scrapping the cab but it's got a clean title so I want to keep the vin in case I come across a buildable truck without a title or a salvage title. Yes,I know it's illegal. But if I can get away with it for registering it as an ORV,that's really all I'm looking to do. Actually,I'm not looking to do that.I'd rather do things legally.but just in case...ya know?
