About 73-87 GMC Chevy Square Body Truck Parts
The 1973-1987 Chevy and GMC trucks were GM’s third-generation C/K series. GM’s official name was Rounded Line; nobody uses it. These are Squarebody trucks, and their unusually long fifteen-year production run means parts interchange across more model years than any other era we carry. Everything on this page is built for the Squarebody cab and bed, so there is no universal-fitment guesswork.
Sheet metal and interior panels
- Bead rolled firewalls for dash and engine bay restoration
- Radio repair panels for a dash that has been cut for an aftermarket head unit
- Bolt-in cup holders sized for the Squarebody dash
- Stone shields for the leading edge of the bed
The Gate Saver and tailgate hardware
A Squarebody tailgate drops in one motion with nothing slowing it, which is hard on the hinges and cables and abrupt every time. Our Gate Saver strut slows that drop so the gate lowers under control, in both 73-87 and 81-87 fitments, and installs without welding. The rest of the range — latch kits, trunnions, cables and billet letters — is on the tailgate upgrades page.
Billet and bolt-in upgrades
Billet door strikers and door handle and lock deletes for a smooth-sided build, CVF billet hood hinges in 73-80 and 81-87 fitments, hood strut kits, the Sparc Industries Squarebody billet steering wheel, Nu-Relic power window kits, Custom Autosound radios and United Pacific LED lighting. Our hidden fuel filler kit relocates the gas cap into the taillight housing, in a fitment that runs 1973-91.
Rust repair and replacement panels
For rust past patching, we carry Auto Metal Direct replacement body panels for this cab and bed: lower front door skins, inner door bottom repair panels, front fender lower rear sections, footwells, cab floor halves, bed wheelhouses, front bed panels, bed floor assemblies, tailgates, and chrome front and rear bumpers with bracket sets.
If this is not your era
Squarebody replaced the 1967-72 Action Line C10 and gave way to the 1988-98 OBS trucks on the GMT400 platform.
Our Chevy truck VIN decoder reads the 13-character 1973-80 serial and the 17-character VIN used from 1981, and it flags the 1988-91 square body carryovers.
