The Fisher Body Paint Spec was to black out the plenum area on light-colored cars; Styling didn't want to see the black wiper linkage contrasted against body color below it in that area. However, that was "extra work", and was random at best. My original-paint 02D Norwood '69 Z/28 (Fathom Green, white stripes) has Fathom Green in the plenum and on the cowl, but where it has flaked in a few places you can see that there's stripe white under the green, so mine was "greened-out" over the stripe overspray instead of blacked-out. You're likely to find almost anything, I guess.
