This 1975 GMC Jimmy was purchased by the seller out of Tucson, Arizona in 2018 and subsequently underwent a frame-off restoration and modification work that was completed in 2020. The truck was refinished in metallic green and repowered with a 6.2-liter LS3 V8 crate engine backed by a 4L70E four-speed automatic transmission and an NP241C dual-range transfer case. Additional modifications include a black soft top, a new GM Performance wiring harness and ECU, a DeWitt aluminum radiator with SPAL fans, Dakota Digital gauges, snap-in carpeting, Tom Wood driveshafts, a custom stainless steel exhaust system, and more. This final-year square body Jimmy is offered with build receipts and photos and a clean Ohio title in the seller’s name.

The body was disassembled and placed on a rotisserie before it was media-blasted and repainted in the 1970 Chevrolet color of Forest Green Metallic. A new windshield and rubber seals were also installed. Details include chrome bumpers and an aluminum tailgate panel along with an LS3 badge mounted in the grille. The black soft top can be seen both installed and removed in the gallery, along with photos of the truck in as-found condition and during the restoration.

Chrome 15″ wagon wheels wear 31″ BFGoodrich All-Terrain T/A tires, including the matching spare housed in the rear cargo area. Manually-locking Warn hubs are featured up front, and new brake components have been installed along with polyurethane suspension bushings and dual steering dampers. The truck was optioned with the Trailering Special package from the factory and has a GVWR of 6,300 pounds as seen on the chassis tag in the gallery.

The interior is trimmed in saddle vinyl with woodgrain accents on the doors and dashboard. Spray-on bed liner and snap-in carpets were added to the floors, an air conditioning system and a body-colored roll bar were installed, and the vent windows were rebuilt. A period eight-track cassette player with an ELO tape is fitted in the dash but not hooked up.

A factory two-spoke steering wheel frames configurable analog-look Dakota Digital gauges including a 150-mph speedometer, a tachometer, and readouts for voltage, oil pressure, fuel level, and coolant temperature. The digital odometer is said to show four miles since installation, and total chassis mileage is unknown. A stainless steel door has been added to the cargo floor for access to the in-tank fuel pump.

The 6.2-liter LS3 V8 was sourced from GM Performance and is fitted with a cold air intake. Cooling is from a DeWitt aluminum radiator with a pair of SPAL electric fans. A GM Performance wiring harness and ECU were installed along with an Optima Redtop battery. The H-pipe dual exhaust system is made of custom-welded and clamped stainless steel. The engine is still under GM Performance warranty according to the seller.

Power is sent to the rear or all four wheels via a 4L70E four-speed automatic transmission and an NP241C dual-range transfer case, both of which are said to have been rebuilt. Additional drivetrain details include Tom Wood driveshafts, Moog U-joints, 3.73:1 differentials, and a custom welded and clamped stainless steel H-pipe exhaust system with catalytic converters.
