Legally Register Any Car

Ca requires: "The last issued out-of-state registration certificate or current year renewal notice, or a letter, fax, or
wire from the last registration jurisdiction verifying the registered owners name(s) and the vehicle’s last
registration expiration date."

I'm not sure if this would be a problem on a legit farm truck or barn find unless the vehicle belongs to an estate that is in probate or something. This was my case on a farm truck I was interested in within ca that could only produce a bill of sale from a deceased "family friend" owner. I just wanted it for the straight frame and various parts ..I'd keep the cab and Vin of my truck if the frame was not vin mark matched. It would have to be a real peach for me to try this end around loop hole CF.
