In September 1965, Ford Motor Company introduced factory-installed and
dealer-installed eight-track tape players as an option on three of its 1966
models (Mustang, Thunderbird and Lincoln), and RCA Victor introduced
175 Stereo-8 Cartridges from its RCA Victor & RCA Camden artist’s
catalogs. By the 1967 model year, all of Ford’s vehicles offered this
tape player upgrade option.
