High Sierra trim (Z84):
Upper intermediate luxury trim- Option code Z84
Trim theme: This was a truly a luxury level trim and was only a very small notch below the top-of-the-line option. It represented the greatest price jump between levels, and in most years, appeared almost identical to the YE9 trim noted below. In all years, a more deluxe molding package, along with a tailgate insert for Fleetsides, was included. Inside, many major additions to the Z62 level were found, including cut-pile carpeting, and insulated full headliner, and door trim panels with large wood grain or brushed aluminum door appliqués. The door panels also had map pockets. Special hood and cab-to-fender insulators were also found here. Because of the near redundancy of this trim with respect to the YE9 level below, I suspect, option Z84 was discontinued after the 1985 model year.
