1000 — T-body (1983–1987)

1984–1985 Single-source

matched to the unit by meaning: carwhere.com's 1984 and 1985 Pontiac 1000 pages list a 1.8L 4-cyl diesel, and Wikipedia's Chevette article says 264 diesel-engined Pontiac 1000s were sold in 1986, with the diesel dropped for 1987; none prints the RPO code; the NICB Pontiac table's 1.8L diesel (VIN letter D, 1984–1986; 1987 manual p.77) is not model-specific and is not relied on; 1986 is not claimed because the 1986 Chevette kit page has no readable model year; shared T-body code; cited from the Chevrolet Chevette kit
