Chevrolet did not retain any records on combinations of options. This means it is impossible to know how many of any particular series and body style came with any combination of options such as how many convertibles were built with a 4-speed and/or a specific optional engine or how many 2-door sport coupes came with a radio.

* Figures based on Len Williamson's Tailfins & Bowtie publication.
** Although no RPO L35 396/325hp engines are listed, there are documented 1968 Chevelles with the L35 engine option that are NOT SS396 Chevelles.
