I. Why the Square Body Endures: A Legacy of Utility and Style

1973 To 1987 Chevy Trucks For Sale: A Comprehensive Buyer’s Guide

The enduring appeal of the 1973-1987 Chevy truck lies in its harmonious blend of utilitarian design, robust engineering, and timeless aesthetics. When first introduced in 1972 as the 1973 model year, these trucks represented a significant departure from their predecessors, offering a more car-like interior, improved ride quality, and a wider range of comfort and convenience features. Yet, they retained the fundamental ruggedness that truck buyers demanded.

Their "Square Body" moniker perfectly describes their iconic, boxy lines – a stark contrast to the more aerodynamic designs that would follow. This design, however, is precisely what makes them so desirable today. It’s clean, functional, and instantly recognizable. Beyond aesthetics, their reputation for reliability, ease of maintenance, and an abundance of readily available parts (both OEM and aftermarket) makes them an attractive proposition for both seasoned mechanics and first-time classic car owners. Whether you envision a period-correct restoration, a modern LS-swapped performance truck, an extreme off-road beast, or simply a cool vintage daily driver, the Square Body provides an incredibly versatile canvas.

II. Decoding the Years: Key Changes and Features (1973-1987)

While often lumped together, the 1973-1987 Square Body era saw several significant design and mechanical updates. Understanding these changes can help you narrow down your search and appreciate the nuances of each model year.

• 1973-1979 (First Series): These early Square Bodies are characterized by their single, round headlights (or stacked dual round headlights on some trim levels). Initial models featured carbureted V8 engines (small-block 350 and big-block 454) and various inline-six options. This period saw the introduction of features like full-time 4WD (initially, later part-time became standard), improved heating and air conditioning, and a more comfortable cab. Trim levels included Custom Deluxe, Scottsdale, Cheyenne, and Silverado, offering varying degrees of luxury and features.
• 1980-1987 (Second Series): The 1980 model year brought a significant facelift, most notably the transition to rectangular headlights (single or stacked, depending on trim). The grille, front bumper, and interior also received updates. Throughout this period, Chevrolet continued to refine the engines, with the introduction of overdrive automatic transmissions (like the 700R4) for improved fuel economy and, crucially, Throttle Body Injection (TBI) in 1987 models. The TBI system offered better cold starting, fuel efficiency, and reliability compared to carburetors, making the ’87 models particularly desirable for those seeking a more "modern" driving experience.
• C and K Designations: It’s important to understand the C and K designations. "C" refers to two-wheel-drive (2WD) models, while "K" denotes four-wheel-drive (4WD) trucks. Both were available across various weight classes (10, 20, 30, corresponding to 1/2-ton, 3/4-ton, and 1-ton).



• Body Styles: The Square Body family was extensive, including:
  • Pickup Trucks: Short bed, long bed, regular cab, extended cab (not widely available until later, but custom options existed), and the highly sought-after crew cab.
  • Blazer: A full-size SUV that offered removable tops through 1975, then partial removable tops until 1991. Highly popular for off-roading and cruising.
  • Suburban: The original large SUV, offering immense passenger and cargo capacity, popular as a family hauler or tow rig.

  

• Powertrains: A variety of engines were offered, including 250 and 292 cubic-inch inline-sixes, and a range of V8s: 305, 350, 400 (small block), and 454 (big block). Transmission options included 3-speed and 4-speed manuals, and various automatics (TH350, TH400, 700R4).

III. What to Look For: A Buyer’s Guide to Square Body Trucks

Buying a vintage truck requires a keen eye and a thorough inspection. Here’s a checklist of critical areas to examine:

1. Rust, Rust, Rust: This is the Square Body’s primary enemy. Check:
   • Cab Corners and Rocker Panels: These are notorious rust traps.
   • Fenders and Wheel Wells: Especially around the tire lips.
   • Bed Floors and Bed Sides: Look for bubbling paint, holes, or patch panels.
   • Frame Rails: Inspect for severe pitting, cracks, or signs of improper repair.
   • Inner Fenders and Core Support: Often overlooked but critical.
   • Floor Pans: Lift the carpet if possible.
2. Mechanical Condition:
   • Engine: Listen for knocks, excessive smoke (blue/black/white), strange noises, or significant oil leaks. Check fluid levels.
   • Transmission: Ensure smooth shifting (manual or automatic), no slipping, and correct fluid color/smell.
   • Drivetrain (4×4): Test 4WD engagement, listen for U-joint clunks, check for differential leaks.
   • Brakes: Check pedal feel, stopping power, and look for leaks at calipers/wheel cylinders.
   • Steering and Suspension: Look for excessive play in the steering wheel, worn ball joints, tie rods, or bushings.
3. Interior:
   • Dashboard: Cracks are common due to sun exposure.
   • Seat Upholstery: Tears, rips, and worn padding.
   • Gauges and Electrics: Test all lights, wipers, horn, radio, power windows/locks (if equipped), and HVAC system. Wiring can be brittle on older trucks.
4. Body and Paint:
   • Look for signs of previous accidents, poor bodywork, or cheap repaints (overspray, uneven panel gaps).
   • Check door, hood, and tailgate alignment.
   • Assess the quality of the paint job – a bad paint job can hide a lot of sins.
5. Paperwork: Ensure the title is clear, matches the VIN, and there are no outstanding liens. Service records, if available, are a bonus.
6. Common Modifications: Many Square Bodies have been modified. Evaluate the quality of any aftermarket parts or custom work. An LS engine swap might be appealing, but ensure it was done professionally. Lift kits should be installed correctly with proper geometry.

IV. Finding Your Square Body: Where to Hunt

The market for 1973-1987 Chevy trucks is robust and diverse.

• Online Marketplaces:
  • Facebook Marketplace & Dedicated Facebook Groups: Excellent sources for local finds and trucks from enthusiasts. Many groups are dedicated specifically to Square Bodies.
  • Craigslist: Still a good spot for local, often lower-priced, projects.
  • eBay Motors: Offers a wide selection, from parts trucks to high-end restorations, often with nationwide shipping options.
  • Specialized Forums & Websites: Websites like ClassicCars.com, Hemmings.com, and specific Square Body forums often list vehicles.
• Classic Car Dealers: Many dealerships specialize in vintage vehicles and often have a selection of Square Bodies, though prices will typically be higher due to reconditioning and markup.
• Auctions: Major auctions (Mecum, Barrett-Jackson) feature high-end, restored examples, while local auctions can yield hidden gems.
• Word of Mouth/Local Classifieds: Don’t underestimate the power of local connections. Sometimes the best deals are found through friends, family, or local mechanics.

Practical Advice: Be patient. The right truck might not appear immediately. Be prepared to travel to inspect a promising lead. Ask for detailed photos and videos before making a long trip. Don’t be afraid to walk away if something feels off. Consider hiring a pre-purchase inspection specialist for higher-priced trucks.

V. Restoration, Customization, or Daily Driver: Your Square Body Journey

Once you acquire your Square Body, its future is in your hands.

• Restoration: For the purist, restoring a Square Body means returning it to its original factory specifications. This involves meticulous bodywork, period-correct paint, original-style interiors, and rebuilt engines/drivetrains. This path often requires significant time and financial investment but yields a truly authentic piece of history.
• Customization (Restomod/Pro-Touring/Off-Road): This is where creativity flourishes.
  • Restomod: Blends classic looks with modern performance and comfort. Popular upgrades include LS engine swaps, modern transmissions, upgraded brakes, air conditioning, and contemporary interiors.
  • Pro-Touring: Focuses on performance handling, with lowered suspensions, performance tires, and powerful engines for track or spirited street driving.
  • Off-Road: Involves lift kits, larger tires, heavy-duty suspension, lockers, and protective armor for extreme trail use.
• Daily Driver: Many owners simply want a reliable, cool vintage truck for regular use. This often involves ensuring mechanical soundness, addressing rust, and perhaps adding modern comforts like improved audio or cruise control.

Regardless of your path, parts availability is a major advantage of the Square Body. Due to their immense popularity, the aftermarket is flooded with reproduction panels, trim, interior components, and performance upgrades. This makes repairs and modifications relatively straightforward compared to many other classic vehicles.

VI. Important Considerations & Potential Challenges

• Rust Repair Costs: This is the most significant potential financial pitfall. Professional bodywork and rust repair can quickly exceed the purchase price of the truck.
• Fuel Economy: With carbureted V8s, don’t expect Prius-level MPG. Even later TBI models aren’t fuel sippers by modern standards.
• Safety Features: These trucks lack modern safety features like airbags, ABS, and crumple zones. Drive defensively.
• Insurance: Consider classic car insurance, which often offers better rates and agreed-upon value coverage than standard auto insurance.
• DIY vs. Professional: Be realistic about your mechanical skills. While many repairs are simple, complex engine work or body restoration might require professional help.

Prices for Square Body Chevy trucks vary wildly based on condition, model year, trim level, engine, transmission, body style (Blazers and Suburbans typically command higher prices than pickups), originality, and modifications. The following table provides a general estimated range in USD, but always remember that market conditions, location, and specific vehicle details heavily influence the final price.

Condition Category	Description	Estimated Price Range (USD)	Key Considerations
Project/Parts Truck	Non-running, severe rust, major mechanical issues, incomplete, suitable only for parts or full frame-off restoration.	$1,000 – $5,000	Requires significant investment in time and money; often more than the final value.
Driver Quality	Runs and drives, functional, but has noticeable rust, worn interior, minor mechanical issues, or rough paint.	$5,000 – $15,000	Good starting point for a rolling restoration or a budget-friendly daily driver.
Nicely Maintained/Restomod	Solid body with minimal rust, decent paint, reliable mechanicals, clean interior, potentially with tasteful upgrades (e.g., LS swap, modern wheels).	$15,000 – $35,000	Enjoyable as-is, can be driven regularly, good foundation for further customization.
Show Quality/Restored	Frame-off restoration, pristine condition (body, paint, interior), period-correct or high-end custom build, often with low mileage post-restoration.	$35,000 – $80,000+	Investment-grade, ready for car shows, premium examples can fetch significantly more.

Note: Blazers and Suburbans generally command prices at the higher end of these ranges, and often above, especially for well-preserved or restored examples. Crew cab trucks also tend to be more valuable due to their rarity.
