The AutoMeter billet dash panel adapts American Muscle gauges for 1954–1955 GMC truck dashboards, offering two 5‑inch and four 2‑1/16-inch openings. This gauge kit positions larger 5" instruments alongside standard 2‑1/16" gauges to modernize instrumentation while matching factory dash contours, simplifying installation and retaining accurate mounting locations for those GMC truck applications.
