Depending on your state I guess, but in Indiana, they don't inspect vehicles as in other states. That being said, who is to say an Indiana vehicle ends up in a state where they DO inspect and it would become an issue? Hmm.
I know that I am in for some radar time when it comes to inspections, as I am building an LJ from a totalled vehicle. In OHIO, when one is totalled, the salvage yard is required to remove tags and VIN plates from the vehicle. I am going to be registering my jeep with an 'assigned VIN' from the BMV, and am sure they will want to see what ID I have for it if any.
Where though on a frame is the VIN stamped? I have not seen it yet, but then again I may not be looking in the right area. To my knowledge it may not even be on there to create an issue.
What is understood need not be discussed.
