1973 To 1987 Chevy Trucks For Sale: Your Ultimate Guide to the Iconic Square Body Era

The third generation of Chevrolet C/K trucks, spanning from 1973 to 1987 (and 1991 for R/V series Suburbans and crew cabs), marked a significant departure from their predecessors. Designed for a wider audience, these trucks introduced more car-like interiors, improved ride quality, and a focus on aerodynamics, despite their boxy appearance. Their instantly recognizable, angular lines and robust stance earned them the "Square Body" moniker, a term that has become synonymous with their enduring legacy.

What makes them so appealing today?

• Timeless Design: Their straightforward, no-nonsense styling has aged remarkably well, making them popular for restoration, customization, and daily driving alike.
• Rugged Durability: Built with heavy-gauge steel and robust drivetrains, these trucks were engineered to last, often enduring decades of hard work.
• Mechanical Simplicity: Many components are mechanically straightforward, making them accessible for DIY enthusiasts and relatively inexpensive to maintain and repair.
• Versatility: Available in numerous configurations – from basic work trucks to well-appointed luxury models – they can serve a multitude of purposes, from hauling and towing to cruising and off-roading.
• Nostalgia and Pop Culture: Featured in countless movies, TV shows, and music videos, the Square Body evokes a strong sense of nostalgia for many, solidifying its place in American culture.

Key Models and Configurations

The Square Body lineup offered an impressive array of choices, allowing buyers to tailor their truck to specific needs. Understanding these variations is crucial when searching for the right vehicle.

C/K Series Designations

• C-Series (C10, C20, C30): Denotes two-wheel-drive (2WD) models. C10s (half-ton) are generally the most popular for their lighter duty and more comfortable ride, while C20s (three-quarter-ton) and C30s (one-ton) offer increased hauling and towing capacities.
• K-Series (K10, K20, K30): Denotes four-wheel-drive (4WD) models, prized for their off-road capability and utility in challenging conditions. K10s are highly sought after, especially short-bed variants.

Cab Styles

• Regular Cab: The most common and traditional two-door configuration.
• Extended Cab (Club Cab): A less common option offering a small rear seating area or additional storage behind the front seats.
• Crew Cab: A full four-door configuration, offering seating for six. These are rarer and highly desirable, especially 4×4 versions, often commanding a premium.

Bed Lengths

• Short Bed (6.5 ft): Typically found on C10/K10 models, these are favored for their sportier appearance and maneuverability.
• Long Bed (8 ft): Common across all series, offering maximum cargo capacity.

Trim Levels

Chevrolet offered a tiered trim structure, ranging from basic work trucks to more luxurious daily drivers:

• Custom Deluxe: The base model, spartan but functional.
• Scottsdale: A step up, offering more comfort features like improved upholstery and chrome accents.
• Cheyenne: Added more amenities, often including upgraded interior trim, power options, and more exterior brightwork.
• Silverado: The top-tier trim, boasting the most luxurious interior with velour upholstery, full instrumentation, air conditioning, and extensive chrome and trim.

Engine and Transmission Options

A wide range of powertrains was available throughout the Square Body’s production run:

• Inline-6 Engines: The durable 250 ci and 292 ci straight-six engines were workhorses, known for their reliability and torque.
• Small-Block V8s: The ubiquitous 305 ci, 350 ci, and 400 ci V8s were the most popular choices, offering a balance of power and efficiency. The 350 (5.7L) is arguably the most common and easily serviceable.
• Big-Block V8s: The powerful 454 ci (7.4L) V8 was available in heavier-duty trucks (C20/K20 and C30/K30), perfect for serious towing.
• Diesel Engines: The 6.2L Detroit Diesel V8 was introduced in the early 1980s, offering improved fuel economy for the time.
• Transmissions: Manual options included 3-speed and 4-speed units (like the SM465 "granny low"). Automatic transmissions included the robust TH350 and TH400 (heavy-duty), with the fuel-efficient 700R4 (with overdrive) introduced later in the era (post-1981).

What to Look For When Buying: Important Considerations

Purchasing a vintage truck requires a careful inspection. Here are the critical areas to scrutinize:

1. Rust and Body Condition

Rust is the archenemy of the Square Body. Common problem areas include:

• Cab Corners and Rocker Panels: Check thoroughly, especially underneath.
• Fender Wells and Dog Legs (behind front wheels): Prone to rust from road spray.
• Bed Floor and Inner Fenders: Especially around wheel wells and drain holes.
• Door Bottoms and Jambs: Water collects here.
• Frame: Inspect for significant rust, cracks, or previous repairs. Surface rust is common, but deep pitting or rot is a red flag.
• Windshield and Rear Window Channels: Rust here can lead to leaks and further body damage.

2. Engine and Drivetrain

• Engine: Look for oil leaks, excessive smoke (blue for oil, white for coolant, black for rich fuel), strange noises (knocks, ticks, rattles), and proper idle. Check fluid levels and condition.
• Transmission: Ensure smooth shifting, both up and down. For automatics, check fluid color and smell. For manuals, test clutch engagement and listen for grinding.
• 4WD System (K-series): Engage 4-high and 4-low. Listen for clunks, grinding, or binding. Check front axle and transfer case for leaks.
• Differentials: Listen for howling or whining noises, especially during acceleration and deceleration.

3. Suspension, Steering, and Brakes

• Suspension: Look for worn bushings, leaky shocks, or broken springs. Bounce each corner of the truck to check shock absorber effectiveness.
• Steering: Check for excessive play in the steering wheel. Inspect tie rods, ball joints, and the steering box for wear or leaks.
• Brakes: Test pedal feel (should be firm, not spongy). Listen for grinding or squealing. Check for even braking. Look for leaky brake lines or calipers.

4. Interior and Electrical

• Dashpad: Cracks are very common.
• Seats and Upholstery: Check for tears, stains, and foam condition.
• HVAC System: Test the heater and air conditioning (if equipped). AC systems often need charging or conversion.
• Gauges and Lights: Ensure all dashboard gauges (speedometer, fuel, oil pressure, temp, voltmeter) work. Test all exterior and interior lights.
• Windows and Locks: Test manual or power windows and door locks.
• Radio: Original radios often don’t work or are outdated.

5. Paperwork and History

• Ensure a clear title in the seller’s name. Verify VIN matches.
• Service Records: Any maintenance history is a huge plus.
• Accident History: Ask about any previous accidents or major repairs.

Where to Find 1973-1987 Chevy Trucks for Sale

The market for Square Body trucks is robust, offering several avenues for finding your next project or pristine classic.

• Online Marketplaces:

  • Facebook Marketplace: Excellent for local listings, often with detailed photos and direct seller communication. Join Square Body-specific groups for targeted searches.
  • Craigslist: Still a good source for private party sales, but be wary of scams.
  • eBay Motors: Offers a wider geographical reach, good for comparing prices, but factor in shipping costs.
  • Bring a Trailer / Cars & Bids: For higher-end, well-documented, or restored examples, often commanding premium prices.

• Dedicated Classic Truck Websites/Forums: Many sites specialize in classic C/K trucks, offering classifieds and community advice.

• Classic Car Dealers: Reputable dealers specializing in vintage vehicles may have restored or well-maintained examples, often at a higher price but with more assurance.

• Auctions: Major automotive auctions (Mecum, Barrett-Jackson) occasionally feature high-quality Square Bodies. Local auctions can also yield finds.

• Word of Mouth / Local Classifieds: Don’t underestimate the power of asking around or checking local bulletin boards.

Tips for a Successful Purchase

• Set a Realistic Budget: Beyond the purchase price, factor in potential costs for repairs, maintenance, insurance, and any desired modifications or restoration.
• Do Your Research: Understand the different models, common issues, and market values for various conditions.
• Inspect Thoroughly: Bring a checklist and a flashlight. Don’t be afraid to get dirty. If possible, bring a mechanically inclined friend or pay for a pre-purchase inspection (PPI) by a trusted mechanic.
• Test Drive: Drive the truck at various speeds, on different road surfaces, and test all functions. Listen for unusual noises.
• Be Patient: The right truck might not appear immediately. Don’t rush into a purchase.
• Negotiate: Most prices are negotiable, especially for private sales. Be polite but firm.

Common Challenges and Solutions

Owning a vintage truck comes with its quirks, but the Square Body community and aftermarket support make many challenges manageable.

• Parts Availability: Generally excellent. Many reproduction parts are available (body panels, trim, interior pieces), along with a vast supply of new old stock (NOS) and used parts. Drivetrain components are largely shared with other GM vehicles, making them easy to find.
• Rust Repair: This can be costly if extensive. Solutions range from DIY patch panels to professional body shop restoration. Thorough pre-purchase inspection is key to avoiding major surprises.
• Fuel Economy: Not a strong suit. Most V8s get single-digit to low-teen MPG. Solutions include engine swaps (LS/Vortec conversions), EFI upgrades, or optimizing the existing engine.
• Modernization: Many owners upgrade brakes (disc brake conversions), add power steering/brakes (if not equipped), install modern air conditioning, or upgrade lighting for daily usability.
• Insurance: Consider classic car insurance, which often offers better coverage and lower premiums than standard auto insurance for collector vehicles.
