Early in the Mustang restoration hobby, a 428 Cobra Jet Mustang convertible was thought to be a mythical creature, like the Loch Ness monster or Sasquatch. Cobra Jet ragtops were believed to exist, although no one had ever seen one.
Jack Brooks attended numerous Mustang shows in the ‘80s, concentrating on his favorite years – 1969 and 1970. Jack thought a 428 ’69 convertible would be the ultimate pony car. His Mustang pals agreed that surely Ford had built a few, but in all their show-going, nobody had an actual sighting.
