Classic Instruments Releases 1973-87 GM Truck Direct-Fit Cluster

New from Classic Instruments – the 1973-87 Chevy/GMC truck direct-fit cluster. This easy to install cluster delivers modern performance and accuracy, while maintaining a classic look. See more details below.

Official Release:

Classic Instruments was excited to announce the debut of its all-new 1973-87 Chevy/GMC truck direct-fit cluster at the 2017 NSRA Street Rod Nationals show in Louisville, KY. The team had the product on display for viewing in their booth, and eagerly awaits the results of the new product competition where the package is entered.

The “Square Body” cluster is completely electric, and designed for a seamless, direct installation
into the stock dash of 1973-87 Chevy/GMC trucks, Suburbans, and Blazers; it also uses the existing factory bezel during installation to maintain the stock look. One of the many benefits to this package is the ability to choose a near-stock gauge style, or select one of Classic Instruments’ signature styles for a more unique cluster. For ease of installation, the package includes a single-connection wire harness, replacement lens, and all necessary sending units. No need to worry about fuel sending unit compatibility as the cluster features a fuel sending unit selector switch to set it for compatibility with the existing/factory fuel sending unit, so no new sending unit necessary. Additionally, the cluster features the turn signals in the stock location and utilizes the existing or factory gear indicator to maintain the nostalgic integrity of the vehicle. Includes Classic Instruments’ Zeus Speedometer Technology.
