Best Seat Swaps for 1973–1987 Squarebody Trucks: What Fits, What Doesn't, and What to Buy

The factory bench on a Squarebody is worn out on most survivors. A seat swap improves comfort, safety, and appearance. Options range from free junkyard pulls to $1,000+ aftermarket brackets.

COMMON ISSUES WITH FACTORY SEATS

  • Foam collapses after 40+ years — bottom feels like sitting on the springs
  • Vinyl cracks and tears — original materials unavailable for most years
  • No headrests on early trucks — safety concern
  • Bench seat limits visibility and interior layout options

DONOR SEAT OPTIONS

  • Mid-1990s to early-2000s GM truck buckets: bolt-in or near bolt-in on many years
  • Camaro/Firebird buckets: popular choice, require custom brackets
  • S10/Blazer seats: fit some configurations with minor modification
  • C4 Corvette seats: sporty option, require more custom work

BUYING NEW

  • Aftermarket bench covers from TMI, Legendary, or similar: maintains factory look
  • Budget bucket kits from brands like RCI or Kirkey work for drivers who don’t need adjustability
  • Quality reclining buckets from companies like Corbeau or Sparco: comfort + safety

AFTERMARKET SEAT INSTALL

  • Most quality aftermarket seats require universal sliders
  • Always verify seat track mounting width matches floor holes or plan to drill
  • Lap belt delete is common when converting to buckets with shoulder belts

WHAT TO AVOID

  • Cheap seat covers that don’t fit factory mounting points
  • Converting to buckets without proper brackets — loose seats are dangerous
  • Buying used seats without inspecting the frame and belt guides for damage
