Paying tribute to all three gauge designs available over the years (1973-75, 1976-78 and 1979-87), the Retro HD series maintains the beloved Chevy and GMC square-body look while bringing in late-model elements. A bolt-in affair with your stock or aftermarket front bezel (not supplied), the twin TFT message centers give the look of a vintage tumbler odometer, but can be expanded with auxiliary readings to keep you informed. Retains stock gear-indicator and the factory turn signal locations are now LED-lit. The Retro HD series is focused on retaining that stock look without sacrificing the late-model features you love. Every effort has been put forth to incorporate OEM design elements regarding the layout, face styling and indicators. A casual glance may dismiss these as original equipment, but once you hit the switch and the LED backlighting comes on in your favorite color scheme, all doubts will be removed.
