COLOSSAL COLUMBUS
Colorful street rods and street machines filled the huge Columbus Fairgrounds, with an estimated 8,000 cars in attendance. This panorama shows just a small section of the event, and the building in the background is where the swap meet was held.

SENSUOUS AT SUNSET
It’s a mammoth effort—building world-class street rods, that is, and to accomplish the goal generally means employing the skills of craftsmen from all across the country. Dave Tucci Jr. is one of the “young gun” rod builders on the scene right now, but he has enough experience to know that finding the right people is more important than where you find them, but we’re getting ahead of ourselves a bit here.

The Last Roadster
Whether you’re a newcomer to street rodding or a long timer, the name Andy Brizio is almost certainly familiar, and for good reason. He has, in one way or another, been closely involved with this hobby since he was a youngster growing up in San Francisco. Yet after more years and cars than he cares to remember, this street-rodding legend has decided to build one last roadster.

You know your Squarebody’s little habits. The fuel gauge you don’t quite trust. The speedometer that leaves you doing mental math. The temperature needle that makes you wonder whether the engine is getting hot or the gauge is giving up. You might have learned to live with all of it, but that doesn’t mean you should.
If your old cluster has become a collection of educated guesses, it’s time to give it a retirement date. The Intellitronix BG6004 Squarebody digital dash brings modern instrumentation to 1973–1987 Chevrolet and GMC trucks, giving that familiar dashboard a fresh start.
A Squarebody Gauge Cluster Upgrade You’ll Appreciate Every Drive
A good set of gauges earns its keep every time you drive. Watching coolant temperature in traffic, checking oil pressure after the engine warms up, or keeping tabs on charging voltage shouldn’t require wondering whether the instruments are telling the truth.
The BG6004 combines a digital speedometer and tachometer with LED bargraph displays for fuel level, coolant temperature, oil pressure, and voltage. Smoked lenses give the panel a clean appearance, while automatic nighttime dimming adjusts the LED display for driving after dark. Turn-signal and high-beam indicators round out the everyday essentials.
Whether your truck is a weekend cruiser, a daily driver, or a project finally earning some road miles, those are functions you’ll appreciate long after the novelty of a new dash wears off.
Speedometer Calibration for Tire, Gear, and Transmission Changes
Different tires? New rearend gears? A transmission swap? Those upgrades can leave an old speedometer struggling to keep the story straight.
Intellitronix gives the BG6004 one-button speedometer calibration to accommodate changes in tire size, gearing, and transmission. An odometer and trip meter handle mileage tracking, while peak-RPM memory, high-speed recall, and built-in 0–60 and quarter-mile timing add useful extras for performance-minded owners.
You don’t need a show truck to appreciate that flexibility. Sometimes the best upgrade is simply making the dashboard catch up with the truck around it.
Modern Digital Gauges in Your Factory Squarebody Dash
The BG6004 installs into the stock gauge housing, preserving the familiar dashboard layout. The kit includes replacement circuit boards, smoked acrylic lenses, temperature and oil-pressure senders, a speedometer sender, and mounting hardware. Installation involves wiring and trimming portions of the housing for clearance.
Buyers can choose from amber, blue, green, red, teal, or white illumination, with optional GPS speed input, an LS engine swap kit, and a quick-connect wiring harness available to suit the build. Note that the bezel is not included.
That gives you a chance to make the instruments feel like part of the finished interior instead of another item waiting on the project list.
What’s in the Box?
The Intellitronix BG6004 kit includes the core components to replace your Squarebody’s factory instruments:
- Three digital circuit boards covering speedometer, tachometer, fuel level, water temperature, oil pressure, and voltage.
- Three smoked acrylic lenses for a clean, coordinated appearance.
- Water temperature sending unit with a 1/2-inch NPT adapter bushing.
- Oil pressure sending unit.
- Speedometer sending unit.
- Mounting hardware for the gauge panel installation.
The kit reuses your factory gauge housing and bezel, with wiring and some housing trimming required. A new bezel and fuel-level sending unit are not included; the system can use a compatible existing fuel sender.
The GPS speed sender, LS swap kit, and quick-connect wiring harness are optional add-ons.
Replace Your Worn-Out Chevy/GMC Gauge Cluster
There’s plenty worth keeping about a Squarebody. Questionable gauges don’t have to make the cut.
Made in America and backed by a lifetime guarantee, the Intellitronix BG6004 gives you a compelling reason to stop nursing a worn-out cluster along. You’ve put time, money, and effort into a truck you enjoy driving. Give yourself a better view of what’s happening every time you turn the key.
