I too feel that is the answer. When the second owner purchased the car, they went to their local Chevrolet dealership to have the 5/50 "Application for Transfer of Warranty" sheet for the warranty balance transferred into their name. The new plate showed up in the mail with a small directions sheet. The sheet shows you how to cut part of the back cover away and install the new plate. No longer any reason to have the original owner info on YOUR plate. I am in the process of selling some cars that have the plain plate. I purchased a '68 Z/28 not too long ago. It actually came with the ORIGINAL POP with the original owner info. It has the Dyna Tab tape. Which would mean the second owner did not transfer warranty in his name. Danny
