667 made....50 of those were the Gibb COPO'S...rare as gold plated chicken lips, as my friend Eric would say. I have never seen another documented, original driveline 68 L78 Nova...other than the Gibb cars. Have talked to a few folks who say they have them....but
Hope you find one. I would like to know if anyone else in the SYC has one...it is definately a small club.
