    Cadillac Fleetwood Brougham / Brougham — D-body, rear-drive (1983–1992)

    The NICB VIN manuals list the rear-drive Fleetwood Brougham as a Cadillac car line in 1983 (Coupe 2 Dr., body 47, and Sedan 4 Dr., body 69) and in 1987 (series DW), and list the Brougham under the same series symbol DW in 1992; Wikipedia says the Fleetwood Brougham name was shortened to Brougham in 1987 and that the car was built through 1992. No Cadillac RPO list, order guide or Heritage kit for these years is in the archive, and the gm.saturn.team lists named in the brief are for later years and do not cover this span, so the doc holds only powertrain codes, every one single-source from Wikipedia's articles on the car and its engines; no source read ties a transmission other than the 4 speed overdrive automatic (MX0, 1987–1990) and the 4 speed automatic 4L60 (MD8, 1990–1992), an axle, an option, a package, paint or a trim code to this car with a year, so none is listed. That is a gap in the sources, not a finding that nothing was offered.

    Codes

    Engines

    Code Description Years Models/Notes Confidence
    LT8 Engine, 4.1L V8, HT-4100 1983–1985 Cadillac high technology V8; Wikipedia's Cadillac High Technology engine article gives LT8 as the HT-4100 option code and lists the Fleetwood Brougham through 1985, and its Fleetwood Brougham article dates the HT-4100 through 1985 (the articles count as one source); no sibling source read prints the code for this car single-source
    LF9 Engine, diesel, 5.7L V8 1983–1985 the Oldsmobile 350 diesel V8; Wikipedia's Oldsmobile Diesel engine article lists the Fleetwood Brougham through 1985, and the Fleetwood Brougham article dates the LF9 through 1985 (one source); shared code, printed for the Chevrolet Caprice in the Caprice kit's 1983 and 1985 engine pages, which is sibling corroboration only (the Caprice kit's 1984 page names the diesel only in a battery remark, which dates nothing, so 1984 rests on Wikipedia) ⛭ GM Heritage — 1983 Chevrolet Caprice, p.13 ⛭ GM Heritage — 1985 Chevrolet Caprice, p.18 single-source
    LV2 Engine, 5.0L V8, 4 barrel, 307 cu in 1988–1990 Oldsmobile 307 V8; Wikipedia's Oldsmobile V8 engine article lists the LV2 (VIN code Y) for the Brougham in 1988 through 1990, while the Brougham article dates the 307 LV2 from 1987; years are restricted to what both print and 1987 is left out (the Fleetwood Brougham article gives a 307 for 1986 without a code); the articles count as one source; shared B/C-body code, printed for the Chevrolet Caprice in the Caprice kit (1988 and 1990 order guides), which is sibling corroboration only ⛭ GM Heritage — 1988 Chevrolet Caprice, p.14 ⛭ GM Heritage — 1990 Chevrolet Caprice, p.15 single-source
    LG8 Engine, 5.0L V8, 4 barrel, 307 cu in, high output 1986–1988 high output derivative of the Oldsmobile 307 (VIN code 9); Wikipedia's Brougham article says the VIN 9 cars, built from 1986 and found as commercial chassis, generally carry the LG8, and its Oldsmobile V8 engine article lists the Brougham with VIN 9 for 1985 through 1988; years are restricted to what both print (the Brougham article's end year of 1990 and the engine article's 1985 are left out); the articles count as one source single-source
    L05 Engine, 5.7L V8, fuel injection, 350 cu in 1990–1992 Chevrolet 350 V8, optional engine; Wikipedia's Chevrolet small-block engine article lists the Brougham among the L05 vehicles for 1990 through 1992, and the Brougham article dates the Chevrolet 350 fuel injected V8 across the same years, though it prints the code as a slash form (L05/LLO), which names neither code, so the row rests on the engine article's list (one source); no sibling page citable for this doc prints the L05 single-source
    L03 Engine, 5.0L V8, fuel injection, 305 cu in 1991–1992 Chevrolet 305 V8 that replaced the LV2; matched to the Brougham by meaning only: Wikipedia's Brougham article names the Chevrolet 305 fuel injected V8 for these years and the Chevrolet small-block engine article lists the Brougham among 305 vehicles for 1991 and 1992, but neither prints the code (one source); the code is the Chevrolet Caprice's 5.0 liter V8 with electronic fuel injection, printed (as LO3) in the Caprice kit's wagon specification page (no printed model year; the years come from Wikipedia only), which is sibling corroboration only ⛭ GM Heritage — 1991 Chevrolet Caprice, p.6 single-source
