The biggest news for 1977 II's was the availability of the T-Top for only the hatchback, a feature that seemed a few years overdue for the Mustang II. Other changes included an argent-painted horizontal grille for coupes, while all hatchbacks came with black ones. Hatchbacks came standard with 3-spoke sports steering wheels and brushed aluminum instrument panels, while coupes came with new pecan-colored woodgrain instrument panels, replacing the walnut type. An available no-cost option for fastbacks was the front spoiler from the Cobra II. The Cobra II was available in 2 new color combos in addition to the previous ones, White w/Red stripes and White w/Green. The Blue w/White stripes version was dropped.
Cobra II's were built by Ford starting this year. A new option for Ghia's, replacing the Silver Luxury Group, was the Sports Appearance Group, it consisted of Black paint with Chamois half-vinyl roof and interior, vinyl-insert bodyside moldings, pin striping, luggage rack, lacy-spoke aluminum wheels, sport steering wheel, and black engine-turned applications throughout the interior. The reverse color comination could also be had. In mid-model year, the Cobra II received a new stripe treatment, the top stripes became 1 wide stripe, with contrasting thin stripes on either side.
The side stripes moved to the center of the body, similar style of the top ones, with a bolder COBRA across the door. Black rear louvers became standard, along with black window moldings. The Cobra II's hood scoop was turned around, with the opening facing the windshield. The previous color combinations remained. Another mid-year changeover was optional White-painted styled steel, lacy spoke aluminum, or forged-aluminum wheels.
