Wow!This is just another case of the 'Net astounding me.Perhaps I should explain.I have read your name as the author of MANY magazine articles over the years.The one particular article that comes to mind is from a late 80's Car Craft Camaro special edition entitled "Skunk Works: An Inside Look At Chevrolet's Blistering COPO Camaros".This and my mid 80's version of Ed C's ZL-1 handbook (yes Ed ,I was one of the masses that sent for this after reading about ZL-1 #3 in Hot Rod circa 1983) are two of my most referred to sources regarding 9560/61's.I'm a frequent reader of this board (but alas, not too often a contributer..) and it's because of the involvement of people like the above mentioned that I consider this site an informative and entertaining source for COPO esoterica.
Thanx for reading this unintentionally long post guys.

PS: when my wife was asked what she thought COPO
was an acronym for,she responded "Cars Other People Own".Too true...Later
