Used grill/cowl between the hood and the windshield from a 1979-83 Mazda RX7FB - 8871-50-791A.  (The difference between these years and the 84/85 models is the single versus two windshield washer nozzles holes and the size and shape of the "grill" part - this is 14.5x4").  This one shows no corrosion, some minor scratching and is black.  If you look closely you'll see a slight bend in a couple of spots where someone may have rested a hand, but not on the "grill" parts.  Overall it is in very good condition.
