In the rear of the '66, 2 Brothers added 5-inch Atlas leaf springs, a 4-inch Pro Comp lift block, and Pro Comp MX6 reservoir shocks, which got the business end up in the air. Making the rear smoke those Toyo tires is a Duramax diesel, tuned by RBP, with a one-off wiring harness from RBP that was expertly wired by Clint Faugust of Scotty's Auto Salvage. An Amsoil intake filter keeps the dirt out, while a turbo-back exhaust from RBP helps the diesel breathe easier. Helping the 6.6L run at peak operating levels, Amsoil fluids were used throughout. Both driveshafts were heavily modified, as the front received some inches and the rear lost some. Two Optima batteries were stealthily mounted in the low-profile black toolbox. A trick mod performed on the gas tank saw Dave use the stock filler neck on the B-pillar, but run the hose through the cab, down through the bed, and into the stock '06 Chevy tank. It's classic looks with modern performance, a theme that resonates in this entire build.

Before painting the truck, the 2 Brothers crew added some cool body pieces to the '66. Out back, Dave cut and widened an '04 Dodge Ram bumper and frenched the edges to fit the rear fenders perfectly. The bed floor was raised 5 inches to help cover up the extra large framerails, then a Chevy Bow Tie was physically burned into the wood bed floor for a distinctive look. Delivering the truck to Bill Matthews Auto Body, Eric and Steve performed the bodywork to get the good body into even better shape. Jeff Schroeder from Attitude Airbrushing then stepped in and applied the charcoal and black colors to the '66 body. The look is classic and timeless. New '66 headlights (with daytime running function, thanks to the new wiring harness), a painted front bumper, and custom Project Matt Hughes billet badges round out the body mods.

Opening the doors reveals an interior designers could only dream of in 1966. The 2 Brothers team swapped in the factory front power seats and covered them in Roadwire black leather and charcoal suede. Using the '06 tilt steering column, the guys capped it with a 15-inch Billet Specialties steering wheel. Nine different Auto Meter gauges were used in the interior, providing Matt with instant engine data. A Vintage Air A/C system keeps the cab cool, and most of the dash was built at 2 Brothers. Behind the seats, a 10-inch Kenwood sub is powered by a Boston four-channel amp. Boston coaxials were mounted in custom kickpanels, also built by 2 Brothers. A Kenwood head unit keeps the tunes flowing. Custom carpet keeps the interior looking great and one-off polished steel pieces were used to add some old-skool looks.
