There was a company called Yenko Motorsports in Vista, California that was selling Yenko items. They also did the 68 COPO 427 Yenko Camaro "One And Only On The Planet" Sweepstakes. I purchased some Yenko items from them years ago and at the time the person on the phone told me they had the rights to the Yenko name. I don't know what happened to the company or the car -- haven't heard anything about either one for a while. here is an old link
