2. Understanding the Square Body Lineup: Models and Years
The "Square Body" era encompasses a range of Chevy and GMC trucks and SUVs. Here's a breakdown of the key models to help you narrow your search:
- C/K Series (1973-1987): This is the core of the Square Body lineup.
- C: Two-wheel drive (rear-wheel drive)
- K: Four-wheel drive
- 10: Half-ton (1500 in later years)
- 20: Three-quarter ton (2500 in later years)
- 30: One-ton (3500 in later years)
- Suburban (1973-1991): The full-size SUV variant of the C/K series.
- Blazer/Jimmy (1973-1991): The shorter, two-door SUV version.
- Crew Cab (1973-1991): Available in both C and K configurations.
Key Year-Specific Considerations:
- 1973-1979: First generation Square Bodies. Known for their simple grilles and often lacking in modern amenities.
- 1980-1987: Second generation Square Bodies. Received a facelift with a more modern grille and improved interiors. Electronic spark control was introduced in some models.
- 1981: Introduction of the Computer Command Control (CCC) system for improved emissions and fuel economy, but often considered a source of complexity by some enthusiasts.
- 1988-1991 (Suburban, Blazer/Jimmy, Crew Cab): While technically not part of the initial Square Body run, these models retained the Square Body style until their redesign in 1992.
3. Assessing the Condition: A Crucial Step
Before committing to a purchase, a thorough inspection is paramount. Here's what to look for:
- Rust: This is the Square Body's nemesis. Pay close attention to the rocker panels, cab corners, floor pans, bed sides, and around the windshield. Rust repair can be costly and time-consuming. Use a magnet to check for filler; if it doesn't stick, there's likely body filler hiding rust.
- Engine: Check for leaks, unusual noises, and smooth operation. Ask about maintenance history. Common engine options include the 350 cubic inch (5.7L) small-block V8, the 400 cubic inch small-block V8, and the 454 cubic inch (7.4L) big-block V8. Consider a compression test to assess engine health.
- Transmission: Test the shifting, both automatic and manual. Listen for slipping or clunking. Check the transmission fluid level and condition.
- Suspension and Steering: Inspect the shocks, springs, ball joints, and tie rod ends. Look for excessive play in the steering wheel.
- Brakes: Check the brake pedal feel and stopping power. Inspect the brake lines for leaks.
- Interior: Assess the condition of the seats, dashboard, and door panels. Replacement parts are available, but restoration can add up.
- Frame: This is the backbone of the truck. Look for rust, cracks, or signs of damage.
4. Where to Find Square Body Trucks For Sale
- Online Marketplaces: Websites like Craigslist, Facebook Marketplace, and Hemmings are popular platforms for private sellers.
- Classic Car Auctions: Auctions can be a good place to find well-restored examples, but be prepared to pay a premium.
- Classic Car Dealers: Dealers specializing in classic cars often have a selection of Square Body trucks.
- Local Classifieds: Don't overlook local newspapers and bulletin boards.
- Word of Mouth: Let your friends and family know you're looking for a Square Body; you might be surprised at what turns up.
5. Negotiation and Price: What to Expect
The price of a Square Body truck can vary widely depending on its condition, model, year, and location. A rusty project truck might sell for a few thousand dollars, while a fully restored show-quality example could command tens of thousands. Research comparable sales to get a sense of the market value. Don't be afraid to negotiate, especially if you find issues during your inspection. Be prepared to walk away if the seller is unwilling to budge on price or address your concerns.
