The 1973–1987 Square Body C/K trucks on this page run the full spectrum — from a lifted two-tone blue and white '79 with a roll bar to a big-block '78 sporting a 454 badge parked in the snow, plus rigs deep in mud and others stripped down to bare engine bays mid-restoration. These builds capture everything that makes the Square Body iconic: off-road capability, weekend mud runs, winter workhorses, and long-haul restoration projects documented one photo at a time.
