I have a small lettered Cobra intake that l purchased a couple of years ago to put on a 65 Mustang project that l am working on. After realizing that these are factory intakes and they do not reproduce them, l think it is worth to much to someone who needs it for a restoration project. It is the small letters at a slant with only the firing order on the back, no part number. The intake is also listed on ebay with the option to remove from auction.
