I have seen the Chevy classics addvertised as Chevelle by mallibuis this correctIs 67 Malibu ss classified sport coupe Or is only ss?

There's some confusion in your question. "Chevelle Malibu" is correct. The Malibu was a *model* within the Chevelle line. Think of it like this: Chevelle was the overall car line, and Malibu was a trim level (a more upscale version).

A 1967 Chevelle Malibu SS is classified as a sport coupe. The "SS" denoted the Super Sport package, which added performance features. So it's both a Malibu *and* an SS. The SS package was available on various Chevelle body styles, including the coupe.
