My Plum 67 RS Z28 is one Bob Harris bought out of Socal about 1990. The video he took back then detailed stripe dimensions etc as it was orig. paint. I was told the other day when I showed someone the car that the hood was not orig.because of the plate shown in the pic. Was told it is not assembly line but later over the counter. Bob is sure it was the orig hood unless someone replaced it later.
Did you read through this Charlie?....Joe

I have looked at a lot of hoods. Have never seen that bracket on an original.
