The Bel Era III direct-fit package offers the perfect combination of all-electric technology and the nostalgic stock look of 1955-'56 Chevys. Built with an injection molded housing and dual-layer design, it provides a speedometer, fuel gauge, oil, temp, and volt gauges all in one easy to install cluster. New to the Bel Era III is a fuel sender selector switch to easily choose the correct resistance range during installation.
