I went through this with my rod a few years back , and I live in Kansas , The leading rectangle state. I had no identifing numbers on any part of the car. I went through a lawer and it took months to get a title. I ended up with the state of ks asigning me a title and registraion plate they istall on the car. It was quite expensive. Had to have a state trooper stamp a number in my frame. When the trooper was there he told me I could have made it a lot easier if I would have had a bill of sale from KS with some matching number on the car. He said it did not mater what the number was , but it had to match up with the bill of sale. I could have stamped any number in or on the car and had a freind write me a bill of sale and that would have been good enough. Seems I always learn the hard way.
hope this helps
