    Chevrolet Impala SS — seventh generation, Caprice-based (1994–1996)

    The seventh-generation Impala was the Impala SS four-door sedan, a 5.7L V8 version of the Caprice Classic sedan (Wikipedia): the 1994 order guide lists it as model 1BN19 and the 1995–1996 guides as 1BL19, and NICB's 1997 manual lists the IMPALA SS under series BL. The 5.7L V8 (LT1) with the 4 speed automatic (MX0) is the only power team on the guides, with the 3.08 limited slip axle; Wikipedia adds the Arlington, Texas plant and gives black as the only 1994 color. The rows come from the GM Heritage Center kits: the Impala SS order-guide pages of each year, the Impala SS MVMA power-teams, engine, transmission, convenience and curb-mass pages (1995–1996), the 1996 LT1 powertrain page, the 1996 dealer feature page and the MVMA optional-equipment weight sheets. The weight sheets are a lightly edited copy of the Caprice Classic sedan's sheet, with police, taxi and wagon items still printed (the 1994 sheets are headed Caprice Classic Sedan; the 1995–1996 sheets are headed Impala SS Sedan, and the 1995 kit's weight pages 40, 44 and 45 are headed Model Year 1994 1/2, issued 6-94, with an AAMA-95 footer), so a code that rests on them is kept only when the Impala SS guides or their standard equipment summaries name its equipment for this car, and only for the years a sheet headed with that model year (or the year's order guide) prints it; the 1995 years that only the 1994 1/2 pages support are left out, a sheet line is not used for a year whose order guide prints the item only as a preferred equipment group row or inside a package's contents, and the rest of the sheet codes are left to the caprice-gen4 doc. Years whose pages print a code with an S for a 5, a B for an 8 or another unaccepted misreading are left out, and the 1995 group codes other than 1SK and the Dark Cherry Metallic paint code have no page that prints them legibly. The 17 inch wheel (QA0) and tire (QBJ) are cited to 1994 kit p.60, a weight page of the same series that KIT-PAGES leaves off the RPO list.
