Although this basic powerplant continued to power the GT500 with modifications through 1970, stylists ensured that the Shelby GTs retained their own unique identities.

For 1968, the GT500 was comprehensively updated with an aggressive new front-end treatment including a lengthened hood line, air scoops and louvered cooling vents, while a neatly integrated rear spoiler was added, as well as revised head and tail lamps, with the rear units being from the 1965 Thunderbird.

Inside, a neatly covered roll bar with inertia-reel shoulder belts was added, and for the first time, handsome convertible variants of both the GT350 and the top-line GT500 appeared.
