Erik Wallgren sent his 1976 Ford F-250 Highboy Fat Fender Garage in Arizona for modern power and new interior. Under the hood they swapped a third generation 5.0 L Coyote V8 making 480 hp (353 kW) and 415 lb-ft (562 Nm) of torque. Behind that is a 10R80 ten-speed automatic transmission and modern F-150 transfer case. Fat Fender Garage upgraded the suspension with new leaf springs and power steering. In the cabin they installed a black leather bench seat, custom door cards, new headliner, Dakota Digital gauges, and Sparc steering wheel.
