1977 GMC K15 Pickup

Officially named the "Rounded-Line" trucks by GM, the 1973-1987 Chevy C/K trucks were known more casually as the "box-body" or "square-body" pickup. Sporting a new body style that incorporated rounded corners around the wheel well in addition to a rounded windshield and door frames, the third-generation Chevy C/K trucks had an entirely new look. Larger and wider, the pickups looked more box-like, which is why they were coined the "box-body" trucks.

For consignment, a 4x4 Sierra, a comfy driver, a short bed with bedliner, a new transmission, and all wrapped up in burgundy with 15-inch rally wheels.

Exterior
Known as the rounded line as tagged by GM, the lines appear to be more square and rectangle than anything else. This includes a rectangular grille with square headlights in square bezel panels and a shiny bumper below. Straight burgundy steel wraps all sides and the bed, and all support well minded gaps. Some thin stainless trimmings finish off the wheel wells and a stainless trim spear runs the length of the truck and drops down at the front and rear to meet a lower trim line. We see invasive rust bubbling up on the bedside just behind the driver's rear tire. The bed is covered with a ribbed tuff plastic full liner which even covers the sides and tailgate. 15-inch rally wheels are wrapped by like new 32x11.50R15LT raised white letter BF Goodrich All Terrain T/A all-weather deep tread tires.

Interior
Black molded vinyl buttons up the door panels and these have a nicely contrasting brushed aluminum insert that holds the door release and window crank. This panel is trimmed with a Sheridan border and down below is a carpeted band in black. Inside is a black velour broadcloth covered bench seat with smooth black vinyl bolsters on the sides and front surrounding of this bench. The original dash is intact and looking clean. The dash top is clean and shows no cracking or distortions and the lower is all steel in body matching burgundy. Above is one piece formed headliner, and on the floors is clean medium pile black carpet with deep tread rubber protectors and in the center is the chrome handle shifter for 2 and 4 wheel drive modes.

Drivetrain
A consigner stated original 350ci V8 is topped with a single 4-barrel carburetor and a consignor stated rebuilt TH350 3-speed automatic. This setup throws power rearward to a Dana 60 axle and forward to a Dana 44 axle. The entire engine bay looks original and great with its blue painted block and supple hoses.

Undercarriage
A solid steel frame and undercarriage floor pans, rockers and toe kicks hold a new fuel tank with straps and look good and unrestored. We note some invasive rust on the bottom side of the bed floor. Dual exhaust sends spent gasses to the rear of the truck through twin Flowmaster mufflers and then to the open air behind each rear tire. Leaf springs with power disc brakes are on front, and more leaf springs with power drum brakes are on the back.

Drive-Ability
A quick fire up and the engine came to life! This K15 drove just like a truck should. Adequate acceleration, good braking and it handled all our test track had to offer. All mechanicals were working, and the interior proved to be comfortable and visually appealing.

This mildly restored short bed K15 GMC is a stunner and deserves a serious look if you are a Sierra fan and looking for something that hasn't been run down every trail or hauled well beyond its load capacity. A nice well-kept example with lots of life left in it, remember what was said in 1978...A good truck can be the start of a long friendship.
