In 67 the GT package also included the upgraded suspension.Hello. :welcome
In the 67 model year you could get the GT package on C code cars. The GT package was really only cosmetic in 67, but, they would happily put it on a C code car. On the 65/66 cars, they only put the GT package on cars that also came with a 4bbl, but, in 65/66 the GT package actually meant a little something. You got front disc brakes, dual exhaust, better suspension, and quicker steering along with the stripes and badges. In 67, it was basically just the stripes and badges.
