There was a discussion about this in 2015 on CRG. Can't believe I remembered. Lot's of opinions, including mine. I still stand by what I said that day. It really means nothing. William said,"The NCRS letter shows the car was shipped to Yenko Chevrolet. Here's an extra $5". Will you ever see two exact cars side by side? .. Danny
