Braking was improved and safer because Ford utilized a dual hydraulic system. The optional front disc brakes were also available with power assist. A new engine (to the Mustang) was also added. The 390 cubic inch big block engine was first installed in 1967.
Two new options were the tilt-away steering wheel and fold-down rear seat on the fastback model. Ford spent more money insulating and sound deadening the cars this year. Also added to the option list included cruise control, a folding glass rear window on the convertibles and an Exterior Decor group including a hood with rear-facing louvers that contained turn signal indicators, wheel well moldings as well as a pop-open gas cap. The galloping Pony inserts were not included in the Interior Decor Group option.
The 1967 Mustang GT was a special options package for 1967 which could be added to any of the V8 engine offerings in 1967 with dual exhaust. And it was required with the 271hp 289ci Hi-Po V8. The GT Equipment Group was offered in 1967 and consisted of power front disc brakes, grill mounted fog lights, dual exhaust with quad outlets (except the 200 HP 289), GT gas cap, F70x14 tires, rocker paint stripes and GT or GTA (if an automatic) side emblems. The Mustang GTA was a Mustang GT with automatic transmission. 24,079 Mustangs had the GT option. A Competition Handling Package was also available on top of the GT package and consisted of firmer suspension components, limited slip rear axle and fifteen-inch wheels with wire wheel covers.
