The stamped-metal radio-delete plate is attached by two threaded studs and covers the empty hole in the dash face. Since the '30s, an ever-growing number of Americans ordered their cars with radios. By the '50s, radio equipment was in the majority, so manufacturers designed dashboards with the assumption of radio fitment. It was more cost effective than stamping two distinct dash assemblies (radio/nonradio). Each manufacturer then whipped up delete plates to fill the void for customers preferring the sound of silence.
