Different upholstery patterns and colors were available in the interior of the 1966 Mustang along with a five-dial instrument cluster. Padded sun visors were standard on every Mustang. Standard engine for the Mustang continued to be the 200ci six-cylinder with the three-speed manual transmission. The Cruise-O-Matic automatic transmission now became available with the “K” code, of which only 5,469 “K” code Mustangs were produced.
