I am interested in purchasing a 65 Roadster which does have all correct matching numbers and the seller swears it is the original engine. He will put this in writing. One problem, this car was stolen in the late 60's according to the owner, and California replaced the vin tag with correct vin number under the glove box. The present owner has owned this car for 32 years. The thief removed the original vin tag. How will this affect going after a Top Flight or Bloomington Gold? Do you think it would be possible to get supporting info from California going that far back?
