A new, more modern look came in 1967, along with a new nickname: "Action Line". It was with this revision of the C/K truck that General Motors began to add comfort and convenience items to a vehicle line that had previously been for work purposes alone. Updated styling features for the 1967 Chevy Pickup trucks came with new body sheet metal that helps fight rust. The majority of 10 and 20 series Chevrolet trucks from 1967 to 1972 were built with a coil spring trailing arm rear suspension, which greatly improved the ride over traditional leaf springs. However, the leaf spring rear suspension was still available on those trucks, and standard on 30 series trucks. The front suspension on all Chevrolet trucks were independent front suspension with coil springs. GMC models came standard with leaf springs with coils springs optional; all four-wheel drive models had leaf springs on both axles.
Numerous changes occurred in 1971. First came another new grille design (the "egg crate") for Chevrolet trucks. Second, an additional trim package was introduced: the Cheyenne. These packages consisted mostly of comfort features nicer interiors, more padding and insulation, carpet, chrome trim, and upper and lower side molding and tailgate trim. 1971 was the first year for AM/FM radios factory installed. Finally, the front brakes on all light-duty trucks were switched from drum brakes to disc brakes, resulting in much less brake fade under heavy use. While many prior C/K half-ton trucks had used a six-lug bolt pattern (6 x 5.5") for the wheels, two-wheel-drive models switched to a five-lug pattern (5 x 5–inch bolt circle) common to Buick, Oldsmobile, Pontiac, and Cadillac passenger cars. The 1/2 ton 4 x 4 retained the 6 lug bolt pattern. This bolt pattern would remain the standard through the end of the C/K series.
The 1972 models were virtually similar to the 1971 models, with the only change being the rear view mirror was glued to the windshield rather than bolted to top of the cab, and metal or vinyl-covered flat door panels were no longer available; all trim level door panels were molded plastic with integral armrests and wood grain inserts on Cheyenne and Sierra trim levels. For restoration, it should also be noted that the door and window cranks were slightly longer due to the molded plastic door panels, and the vent windows were now secured with a single screw on the inside of the door, thus differentiating it from the 1971 model year.
We restored this beauty to its former glory that only a 72 Custom 10 would have! Along with these awesome features that came with the truck we decided to add a couple modifications ourselves. We upgraded the driveline from a 2 wheel drive up to the much wanted 4 wheel drive. We added a new stereo deck and Rockford Fosgate sound system. We relocated the gas tank from behind the seat to the back end of the truck under the bed. A new digital dash board with tons of timing options and gauges. We also added custom build side steps and big wheels and tires! You can't have a big truck without big wheels and tires! To top it all off we added a two tone paint job! There aren't a lot of trucks out there that are this good looking and as badly wanted as this truck!
