Here is an original pair of FoMoCo exhaust manifolds that are correct for a 1969 to late 1970 428 Super Cobra Jet. The date code can't be read on the passenger's side but the driver's side appears to be November 18, 1968. The driver has some pitting in between the middle two runner and the passenger on the 3rd flange from the front has minor pitting on the surface as these were ran originally with no gaskets but can be ran with gaskets for easier sealing. They have been magnafluxed and found no cracks.
