This record's own overview states that Tradecraft Specialties lists RPO Z15 as the El Camino's Super Sport package throughout the 1978-1987 run, named "SS Sport Decor" for 1984, and describes it as up-level trim with SS badging and rally wheels rather than a distinct model line. This record's own dek identifies the car as the fifth-generation El Camino, with no production count from a verifiable source found for the SS package itself, a gap the record's later conflicts section addresses only for the total car count, not the SS share.1

This record's own key facts state that 98 of 22,244 El Caminos built for 1984 had the LF9 diesel, and that Choo Choo Customs of Chattanooga produced an El Camino SS conversion for GM from mid-1983 through the end of 1987 production. They add that Chevrolet's data book for 1984 calls RPO Z15 the SS Sport Decor, Diablo Decor on the GMC Caballero, listed at $8,769.00 MSRP against $8,510.00 for the base El Camino, for cars built from February 13, 1984.1,1

This record's own conflicts section documents a genuine three-way production dispute for the year's total: 22,244 from Tradecraft Specialties, 22,997 from Team Chevelle, and 24,244 from Old Cars Weekly, with the record's own treatment explaining that none of the three sources states its own underlying basis, so none is preferred, while noting that the 22,244/24,244 pair differs only in the thousands digit, suggesting a transcription error in one lineage or the other that cannot be determined from the record's own sources.1,2,3

This record's own conflicts treatment also explains that the record previously held the 22,997 figure only as an unverified Wikipedia lead citing the Team Chevelle page, and that having now read that page directly, the figure is promoted to a sourced claim rather than left as a lead, since Wikipedia's own citation of the same page is one claim read a second way rather than a fourth, independent lineage. This record's own unpublished leads section is accordingly empty for 1984, its earlier Wikipedia-sourced content having been resolved into the conflicts section instead of standing apart from the record's other sourced claims.2

This record's own engines section documents a 110-horsepower LC3 229 V6 standard outside California, a 110-horsepower LD5 231 V6 for California only, a 150-horsepower LG4 305 V8 optional at $375.00, and the 105-horsepower LF9 diesel optional outside California at $700.00, nearly double the price of the gasoline V8 option this record documents alongside it. Its transmissions section lists only the MX1 three-speed automatic, described as standard at no additional charge and the only transmission listed for any of the four engines above.

This record's own prices section documents the base El Camino at $8,510.00 against the SS Sport Decor at $8,769.00, a $259.00 gap between the two, noting that the SS row covers the GMC Caballero's Diablo Decor as well rather than being exclusive to the Chevrolet badge. This record's own performance and identification sections are both empty for 1984, a gap it carries without substitution even though its conflicts section carries three separately sourced production totals, each individually attributed, rather than leaving the disagreement unstated.

Where the sources disagree

1984 El Camino total

  • 22,2441
  • 22,9972
  • 24,2443

All three shown; none preferred. This record previously held 22,997 only as an unverified Wikipedia lead citing this same Team Chevelle page; the page has now been read directly, so that figure is promoted here as a sourced claim rather than a lead. Wikipedia's own article states the same 22,997, citing this same page — that is this one claim read a second way, not a fourth, independent lineage. None of the three sources states its own underlying basis (a named factory production report), so none is preferred; the 22,244/24,244 pair differs only in the thousands digit, which suggests a transcription error in one of those two lineages, but which one cannot be determined.
