My6 69 z-28 is a late november (4th week) 68 build date, vin has x33d80(BIG TAG), but has a cowl hood the owner sez was on the car from the factory. By the way it has all of the original cowl stuff. McNeish's book states this is not possible due to the december memo (issued 4th week Nov) not reaching production line until Mid December. Could this have been installed by the dealer? By the way I bought the car in just a little over one million pieces and have it back to running condition now. I have never seen a car this apart in my life, but it is all there!!
