From Parts Runner to Dream Cruiser: Randy & Tobie Johnson’s 1968 C10 “Shop Truck”

Randy and Tobie Johnson never set out to build a showstopper. What started as a simple parts hauler for their Wisconsin-based shop, D&Z Customs, gradually evolved into something more—a stunning blend of classic style, modern comfort, and serious capability. Their 1968 Chevy C10, affectionately nicknamed the “Shop Truck,” still does the hard work it was built for, but it now turns heads while doing it.

A Classic Workhorse Reimagined

Randy, a veteran builder, initially chose the ’68 C10 for its clean lines and utility. With its Mist Blue Metallic finish and no-nonsense stance, the truck was meant to be functional—running errands, hauling gear, and serving as a rolling advertisement for the shop. The original build was straightforward: a reliable LS3 engine, some bolt-on suspension upgrades, and the character of a well-kept classic. But as time went on, each modification revealed new possibilities.

The Johnsons realized they could maintain the truck’s working-class roots while making it far more refined and enjoyable to drive. That evolution led to a transformation—not into a dedicated race machine, but into a thoughtfully built cruiser that’s just as comfortable in traffic or on the interstate as it is parked at a car show.

The Backbone: Speedtech ExtReme Street Chassis

The turning point came with the decision to install a full Speedtech Performance ExtReme Street chassis. This complete frame swap elevated the C10 from a capable hauler to a street-friendly performer with exceptional ride quality and handling. Designed specifically for 1967–72 Chevy trucks, the ExtReme chassis ditches factory limitations in favor of modern geometry, structural rigidity, and real-world usability.

The torque-arm rear suspension delivers smooth, bind-free articulation—a perfect setup for real driving conditions. QA1 coilovers at all four corners allow easy adjustability, meaning Randy can tailor the stance and comfort for any occasion. Whether it’s a Saturday cruise or a long-distance haul, the suspension delivers confident, predictable performance.

Supercharged Muscle That’s Built to Drive

Under the hood, the original 525 hp LS3 crate engine has been enhanced with a Whipple supercharger, turning the already potent V8 into a powerhouse with real-world street manners. Paired with a 4L80E overdrive automatic, the drivetrain delivers both relaxed highway cruising and serious punch when needed. A custom exhaust ensures the truck sounds the part without droning or drawing unwanted attention—just the right balance for a daily driver with bite.

Supporting systems, including Holley EFI and a heavy-duty 9-inch rear with 31-spline axles, provide reliability and confidence for real-world use. It’s powerful, but most importantly, it’s dependable—always ready to fire up and go.

Smart Details for Everyday Use

The Johnsons retained their original Forgeline CR3 wheels, making clever use of custom hubs to adapt them to the new chassis. This allowed them to preserve the truck’s original aesthetic while upgrading its performance foundation. Behind the wheels, Wilwood brakes provide responsive, consistent stopping power—another nod to safety and drivability over flash.

Inside, the truck offers a comfortable, stylish space with Cerullo bucket seats in houndstooth, updated gauges, A/C, and a modern sound system. These additions make the C10 as livable as any modern cruiser, without sacrificing its vintage soul.

Still a Shop Truck at Heart

Despite the upgrades, the C10 remains true to its roots. It hauls parts, tackles road trips, and sees real use. Randy drove it on the Hot Rod Power Tour with under 100 miles on the build and didn’t skip a beat. It’s not a garage queen—it’s a truck that works, just with a lot more style and sophistication than most.

More Than Just a Build

For Randy and Tobie, this C10 is a symbol of what’s possible when you build with intention. It proves that classic trucks can be stylish, comfortable, and fully capable of handling modern driving demands. Their advice? Build it to drive. Focus on the foundation. Make it enjoyable, usable, and dependable. The rest will follow.
