for some reason, i have kept several radios from the late 70's that came from various chrysler products.
i know they worked when i took them out, because i scrapped lots of stuff in the late 80's - mid 90's time frame, even though i had sold my junkyard back in 1984.
i also kept a few "infinity" radios for parts, in case they were needed to repair the cassette deck in my minivan.
and on the shelf they "live".
