text: The Brougham and 500 option packages continued, as did the availability of the Super-Lite, but the 440 Magnum V8 was dropped. The  version 440, available only in wagons for 1969, became the new top engine for all Monacos. Despite all of the changes, which cost Chrysler a rather large sum of money, Monaco (and Polara) sales declined, with 24,692 Monacos built for the model year.
  1971
  The 1971 model year Monaco received a facelift featuring a new grille within the bumper that had been used the previous year, and other minor styling changes focused mainly on the rear. The Super-Lite was no longer available because of a lack of consumer interest and challenges to its legality in some states. A new single-loop rear bumper and larger taillamps were installed.
  The 500 option package was discontinued. A stereo cassette player-recorder with a microphone was new on the option list. Bucket seats remained available despite the loss of the 500 package, and the Brougham package was also available for $220, despite the addition of a separate Polara Brougham series.
  All engines had their compression ratio reduced so they could all run satisfactorily on regular-grade gasoline. The two-barrel 383 versions still has the same power rating , the four-barrel 383 dropped to , and the 440 dropped to .
  Monaco station wagons, which in 1969 and 1970 featured woodgrain trim on the lower bodysides, now had woodgrain high on the sides, including around the side windows. The new vinyl decals were translucent, allowing some paint color to shine through.
