The 428 Cobra Jet equipped Cougar has a satin black hood stripe, extending from inside the hood scoop forward and down over the front, straddling the center bright Mercury emblem. Both the stripe and the hood scoop are satin black. This scoop and stripe are shared with all other 1968 Cougars equipped with the 428 Cobra Jet engine option and applied to all body colors, including black.
Hood Scoop
1968 Cougars equipped with the 428 Cobra Jet option came with a functional satin black hood scoop and matching black stripe. The Satin Black Hood Scoop for the 1968 is unique, as it has 8 mounting studs, where the Eliminator Scoop in 1969 and 1970 used 10 mounting studs. Also unique for 1968, the hood scoop does not have any part numbers molded into the underside.
