This Diamond T 404 is a customized hauler that underwent a partial rebuild and refurbishment in Texas around a decade ago, with work including mounting the cab and flatbed on GMC pickup chassis and the installation of a 350ci Chevrolet V8 and an M22 four-speed manual transmission. The truck was acquired in 2019 by its current owner, who commissioned a repaint in matte black as well as the installation of an air-ride suspension system. Additional features include a diamond-plate bed with a winch and two tool chests along with under-bed storage compartments, a rear receiver hitch, front brush guard, AM/FM radio and an auxiliary input, tow mirrors, body-color steel wheels, and black leather upholstery. This modified Diamond T is now offered by the seller on behalf of its current owner with New Hampshire registration listing the truck as a 1939 Diamond T pickup.
Said to have been previously finished in green, the bodywork was fitted to a 1 1/2-ton GMC dually pickup frame during the initial build, and was repainted its current shade of matte black in early 2022. Exterior equipment includes a custom diamond-plate bed with two tool chests and a winch along with a rear receiver hitch, under-bed storage compartments, a front brush guard, extended mirrors, LED taillights, and dual exhausts that exit ahead of the rear wheels.
Body-color steel wheels are mounted with Dynatrac and Michelin tires. The truck is equipped with an air-ride suspension that was installed during current ownership.
The cabin houses a single bench seat with a folding central armrest trimmed in black upholstery. Black carpets and mats line the floors, and features include a fold-out windshield, diamond-plate lower door panels, a floor shifter, and a push-button AM/FM radio with an auxiliary input.
The wood-rimmed steering wheel is mounted to a chrome steering column and sits ahead of a dark green-painted metal dashboard housing a 100-mph speedometer, a combination gauge, and auxiliary Stewart Warner displays monitoring oil pressure, voltage, and coolant temperature. A pressure gauge and control switches for the air ride system are mounted under the right side of the dash. The five-digit odometer shows approximately 40k miles, though total mileage is unknown.
The 350ci Chevrolet V8 was installed during previous ownership and features an aluminum radiator, a single carburetor, MSD ignition, tubular headers, and a polished and finned air cleaner cover and valve covers.
Power is sent to the rear wheels via an M22 four-speed manual transmission. Additional underbody photos are provided in the gallery below.
The truck is registered using the State of Idaho-assigned VIN shown above.
The truck does not have a title, as it is being sold in a state that does not issue titles for vehicles of its age. It is being sold with its New Hampshire registration, which lists the truck as an antique.
