The new analog/digital guages fit directly into the stock instrument bezel of a 1964-66 chevy pickup without modification, adding a wealth of features to this iconic vehicle. Fully lit needles, backlit faces, and highly visible lcd message centers are a few of the things that you can see which these apart from yesterday's traditional instrumentation. A few of the features which you don't normally see are the micro-controlled precision stepper motors, solid state sensors for unparalleled accuracy and user-customizable display feedback, all supported by an unrivaled limited lifetime warranty.
