Why not opt for a tailor-made instrumentation upgrade instead of adapter rings and a “good enough” finished product?
The stock dash in 1954 and 1955 First Series Chevy pickups (sorry, not GMC) is fitted with custom machined billet aluminum bezels and offers six analog instruments with twin TFT message centers.
Supplied mounting hardware makes installation straightforward.
Available in black or silver alloy gauge-face styling, each HDX system allows independent illumination color selection for the gauge readings and needles, as well as the message centers.
Calibration and personal settings are adjusted with the built-in capacitive-touch buttons or the available Bluetooth app for Apple and Android devices.
Each needle hub is spun-aluminum black nickel plated to match the buttons.
All HDX instrument systems feature dead-faced (hidden) indicators (turn signals, high beam, check engine, cruise control, parking brake, plus two user-definable), and a red, settable warning light for each gauge.
With the central control box, installation is simplified with vehicle-harness sourced signals and supplied solid-state sending units connecting cleanly to their respective terminal.
