Square-body GMC pickups put three people on one bench, and this Seatbelt Planet kit is sold for exactly that layout. It provides belts for the driver, the middle rider and the passenger in a 1973-1987 GMC standard cab, in what Seatbelt Planet calls its all-metal style. Many webbing colors come with plastic trim pieces keyed to the strap, which helps the belts blend into a restored interior.
Vehicle Fit
The title covers 1973-1987 GMC standard cab trucks with a front bench. Seatbelt Planet's description text refers to 1976-87 pickups, so owners of earlier square-bodies should confirm fit before ordering.
Choosing a Color
The option list has 52 webbing shades, 13 of them premium. Seatbelt Planet color-keys the plastic trim on ten shades (the reds, maroon, the tans, beige, navy, gray and silver), uses tan trim with camel, and fits black trim with everything else.
Why Upgrade?
A square-body bench belt set that has spent forty years in the sun is often stiff, faded and slow to retract. Swapping in a complete three-seat kit gives the cab a uniform look and makes every position usable again.
Maintenance
Wash the webbing with lukewarm water and a little mild soap, rinse the plastic trim with a damp cloth, and let everything dry before the belts rewind.
About the 1973-1987 GMC Square-Body
GMC's 1973-1987 trucks, nicknamed square-bodies, were offered as Sierra, Sierra Classic and High Sierra trims, among others. Their roomy bench cabs and simple mechanicals have made them some of the most popular classic trucks on the road today.
Pre-Install Checklist
Tip the bench forward and find the floor anchors for all three positions along with the upper mounts on the cab pillars. Clean every threaded hole and look under the mat for rust.
Good to Know
Matching plastic parts for many colors.
Seatbelt Planet also notes matching thread colors on some webbing shades, a small detail restorers appreciate.
Because the kit covers all three seats, the belts arrive from the same batch of webbing and look identical.
Sierra Classic interiors in blue, red or saddle pair well with the color-matched plastic trim.
Seatbelt Planet sews each kit after the order is placed.
Square-body owners who carry kids in the middle seat value having a working center belt.
Compare the listing image with your cab before ordering if you have an early 1973-1975 truck.
