If you’ve got a classic Pontiac A-body from 1970 to 72—like the T-37, Le Mans, Tempest, or the iconic GTO—you’re probably always on the lookout for ways to bring it into the modern age without losing that vintage charm. That’s where this complete six-gauge instrument system comes in. It’s not just a pretty face; it’s packed with features that make it a must-have for anyone who loves their ride.

First off, let’s talk about the setup. This system fits right into your stock instrument bezel, so you don’t have to worry about any complicated modifications. You can choose between a sleek Black or Silver Alloy face, and the LED backlighting comes in blue, red, or white—whatever suits your style. And yes, new clear lenses are included, so you can ditch those old, foggy ones.

Now, what really sets the MHX Series apart are the details. The fully lit needles and backlit faces make it easy to read everything at a glance, even in bright sunlight. Those twin LCD message centers? They’re not just there for show; they provide real-time data that helps you keep an eye on what’s going on under the hood. And let’s not forget about the micro-controlled precision stepper motors and solid-state sensors—they give you accuracy you can trust. Plus, you can customize the display feedback to fit your needs.

One of the best parts? Dakota Digital backs this system with a limited lifetime warranty. That’s not something you see every day, and it really speaks to the quality of their products. Everything is engineered and manufactured in Sioux Falls, South Dakota, so you know you’re getting something that’s built to last.
