      1988 option-weight page; the 1989–1991 option-weight pages print the code as 221, and the 1990–1992 pages name Z21 only in the custom-interior remark, so those years are not claimed; a GM parts code list reads it as Beretta GT (1LV37 plus Z21 gives 1LW37)

      GM Heritage factory kit — 1988 Chevrolet Beretta, p.35.

    This page aggregates every documented appearance of Z21 in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
