In 1967 GM started producing the GMC and Chevrolet 1/2 ton pickup trucks on the same assembly lines to reduce cost. The light duty GMC trucks were built in the Chevrolet plants, while the medium and heavy duty trucks continued to be produced at GMC Plants. This was, in effect, the end of GMC as a separate small truck division and afterwards there were basically no differences between the two trucks except interior and exterior trim.
The one big visual difference between 1967-1972 GMC and Chevrolet pickup trucks was the grill. GM must have decided they got the GMC grill right the first time because, unlike the 1967-1972 Chevy 1/2 ton pickup trucks, which radically changed grill design every 2 years, the GMC kept the same basic look of the grill for all 6 model years, with only subtle changes. Also, all 1967 through 1972 GMC models had dual headlights and parking lights mounted in the grill.
Like the Chevrolet pickup trucks of the same years, the 1967 through 1972 GMC 1/2 pickup trucks can be divided into three groups for identification purposes. These three groups are each comprised of 2 model years. Each 2-year group is similar in appearance and different from the other 2-year groups. However, the differences between these 2-year groups are more subtle than those of their Chevy siblings.
The 1968 model is almost identical to the 1967 pickup. The most obvious difference is the addition of side markers front and rear to comply with new traffic safety laws. The small rear window is discontinued. Some models have narrow fender eyebrows and chrome hood trim rail. The standard 283 cubic inch V8 was replaced by a 307 cubic inch V8. The 327 cubic inch V8 was still available, along with the new 396 cubic inch V8. The 1968 model still has a hand operated parking brake and drum brakes front and rear.
