I know one parts guy, from back in the day who says that, he remembers the headers and cowl plenum were shipped to the dealer separate from the cars, at least on the Z28s which they ordered.

Does a box of headers, even fit in the trunk along with the factory spare? If I remember correct Milt Robson had a Z28 and the headers were loose, with a special bracket to hold them in place?

Same goes for the X-Ram set up.
