In 1982 the R-body line was discontinued and the New Yorker nameplate transferred to the smaller M-body line.
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.
 The Fifth Avenue (and its Dodge and Plymouth siblings) would prove to be the last V8-powered, rear wheel drive Chrysler vehicles until the Chrysler 300 was revived in that configuration for 2005.

All Fifth Avenues from 1984 to 1989 were powered by a 318 cu in (5.2 L) V8 engine, with either a two barrel carburetor making 140 hp (104 kW) (in all states except California) or a four barrel rated at 170 hp (127 kW) (in California), mated to Chrysler's well-known Torqueflite three speed automatic transmission.
 As this was the largest Chrysler model available, sales took off, especially during 1985-86, when over 100,000 were made each year.

Starting with the 1984 models, Fifth Avenue production was moved from Windsor, Ontario to St. Louis, Missouri.
Beginning in late 1986 through the 1989 model year, they were manufactured at the American Motors plant in Kenosha, Wisconsin (purchased by Chrysler in 1987).

The Fifth Avenue also far outsold its Dodge Diplomat and Plymouth Gran Fury siblings, with a much greater proportion of sales going to private customers, despite its higher price tag.
Production peaked at 118,000 cars for 1986 and the Fifth Avenue stood out in a by-now K-car dominated lineup as Chrysler's lone concession to traditional RWD American sedans.

Although it takes a trained eye to catch changes in the M-body Fifth Avenue, there were a few during its six-year run:
1984 - New Yorker badge replaced by Fifth Avenue badge on trunklid; "Fifth Avenue Edition" badge continues on the rear doors, a new steering wheel was added.
The regular Pentastar was replaced by a crystal one and was now used on the hood ornament and steering wheel this would continue through the end.
Wiper arms were now black (instead of silver).
