They had modified front air dam and a blackout point treatment around the hood scoops.

Ford also made a few 'Sidewinders', which were built in Dearborn, shipped to Omaha, and sold in Iowa and Nebraska. They were available in Grabber Green, Grabber Blue, Calypso Corral, and Yellow. The stripes came in the trunk to be installed by dealers.
