Up to this point, the Chrysler M-body entry had been sold as LeBaron, but that name was moved to a new K-car based FWD line (refer to the Chrysler LeBaron article for information on the 1977-1981 M-bodies). Following the nameplate swap, the M-body line was consolidated and simplified. 360 V8 engines were gone, as were coupes and station wagons (the K-car LeBaron's coupe and wagon replaced them). The Fifth Avenue option was still available as a $1,244 option package. It was adapted from the earlier LeBaron's package, with a distinctive vinyl roof, electro-luminescent opera lamps, and a rear fascia adapted from the Dodge Diplomat, albeit modified. Interiors featured button-tufted, pillow-soft seats covered in either "Kimberley velvet" or "Corinthian leather", choices that would continue unchanged throughout the car's run. In addition, the carpet was thicker than that offered in the base New Yorker, Diplomat and Gran Fury/Caravelle Salon, and the interior had more chrome trim. The Fifth Avenue option also included illuminated entry, AM/FM stereo with a rear amplifier, power door locks, power 6-way driver's seat, power antenna, remote trunk release, dual side mirrors, full undercoating, passenger vanity mirror, tape stripes, locking wire wheel covers, as well as a standard 5.2L (318 in³) V8 engine.  1982 was the last year for the optional AM/FM 8-track stereo, and AM/FM stereo with integrated CB. The exterior of a Fifth Avenue Edition New Yorker can be identified from a regular New Yorker by the following: opera lights, hood stripes, and Fifth Avenue Edition badges on the rear door window filler panels—New Yorkers bore "New Yorker" badges. In another confusing name swap, the New Yorker name was now used for another new K-car line in 1983, the E-body New Yorker and Dodge 600. The larger M-body car was now called New Yorker Fifth Avenue to distinguish it from the E-bodies. 1983 was the last year M-bodies were made in Canada and the last year for the optional "Chronometer" glovebox-mounted clock, the 225 Slant-six six-cylinder engine, and all analog tuned radios and chrome-trimmed pedals. For 1984 the car was simply called Fifth Avenue, setting the name that would continue for six successful years.
