I don't ever recall these. Being around prior to ebay. Back about 15 years ago, I think there was 1 seller in PA who was offering all of these with the 442, GTO, 396 logos etc. I suspected back then they were the manufacturer but the auctions always were written to elude that they may be some rare old cover that happened to be NOS.
If someone can provide any pics, an advertisement, catalog pic I would love to be proven wrong. Until them, I think it is just a modern made part thay has been marketed as being vintag by a small time manufacturer.
