[1967Z28]

I got my green Z from the original owner and it was a factory header and cowl plenum car (with docs). He also worked at the dealership. His was the only Z that the dealership got in '67. He told me the headers and cowl plenum came in the trunk. I got the box for the cowl plenum with the car and it had no address label for the dealership on it. I suspect the headers did not come in a box but may have had some wrap of some sort around them otherwise I probably would have gotten that box too. I also got the boxes for the rally wheel hubcaps as they [and the trim rings] had never been installed. If the headers were boxed, which I kind of doubt, they probably were put in the backseat. If you ordered a Z with cowl plenum or headers, bottomline it came with the car. Exceptions may have been if there was a shortage at the time of the car's build.
