Just a follow up comment....I would imagne most people are well aware of the laws regarding vin switching. But there are legitimate restoration reasons for needing things like original rosette rivets (ie replacement of a 68 firebird dash due to rust out). In such a case, the original vin number plate remains with the original car. So how does Illinois deal with this? I believe other states do not have such restrictions as that which has been pointed out above. I've dealt with california laws. They state that vins can be changed "with authorization from the DMV".
