When Oldsmobile rolled out the redesigned A body platform in 1966, they really hit the sweet spot for muscle cars. The sleek lines and those eye-catching wheel arches made it a head-turner, but it was what was under the hood that kept the competition sweating. Now, if you’re like me, you know that the stock gauges just don’t cut it anymore. Sure, you had the twin round gauges in the dash, but if you wanted anything more, you were stuck hanging auxiliary instruments under there like an afterthought. That’s where the MHX Systems come into play.

This direct fit package for the 1966-67 Oldsmobile Cutlass takes the stock bezel and transforms it into a modern marvel. Sure, you’ll need to do a little tweaking inside the stock instrument housing, but don’t worry—the manual lays it all out clearly. And trust me, once you see what this system can do, you’ll be glad you made the effort.

So what sets the MHX Series apart? For starters, those fully lit needles and backlit faces are a game changer. You’ll appreciate the high visibility LCD message centers, especially when you’re pushing your ride to its limits. But it’s not just about looks; this system packs some serious tech under the hood. We’re talking micro-controlled precision stepper motors and solid-state sensors that deliver accuracy you can count on. Plus, you can customize the display feedback to suit your style. And let’s not forget about the limited lifetime warranty—Dakota Digital stands behind their craftsmanship, and that speaks volumes.

Everything is engineered and manufactured right in Sioux Falls, South Dakota, which is a nice touch for those of us who appreciate American-made quality. The MHX Series isn’t just an upgrade; it’s a revolution in instrumentation.
