The Green Hornet, starring Van Williams and Bruce Lee. A black Imperial of this year would also be restored as a wedding anniversary gift for Richard "The Old Man" Harrison who used to be on the History Channel show, Pawn Stars. Third generation (1967–1968) Imperial styling was completely new for the 1967 and 1968 models. Using a two-inch shorter wheelbase, Imperial switched from the body-on-frame platform (D-body) to a unibody platform (C-body platform used in other full-size "Mopars".) While Imperial's front K member was longer than a Chrysler's, dimensions behind the front fenders were similar. One reason for the change was that Chrysler had gained experience with unibody construction and was ready to apply it to the company's flagship line. The economic component was that the switch to the C-body was less expensive than maintaining a separate platform for Imperial, which was increasingly difficult to justify given Imperial's relatively low sales volume. The new platform resulted in a significant reduction in weight as well as in exterior and interior dimensions. With the partnership gone between Ghia and Chrysler, limousines based on the Imperial were produced by Armbruster-Stageway of Fort Smith Arkansas. The limousines were "sectioned", with 36 inches added, most of that between the front and back doors with a few inches added between the rear door and the rear wheel, allowing room for two rear-facing seats with a small console/bar in between. The limousine conversions were longer than the earlier Ghia cars, and longer than the Cadillac Series 75 limousines. 1967 (Series CY1-M,H) Imperial shared the unibody platform with other full-sized Chrysler Corporation cars, but retained a unique bodyshell. The styling kept the overall straight-line, sharp-edged Engel theme, but there were many detail changes intended to make Imperial look less like Lincoln and more into its own territory. The spare tire bulge was completely gone from the rear, although the boss remained. The practically full-width taillights spread out from it, straight, but ended before chrome-tipped rear wings. A base Imperial model, simply called Imperial, returned for the first time since 1963, complementing the Crown and LeBaron levels of trim. It was the first four-door pillared Imperial sedan since 1960. New standard features included dual brakes with upfront discs and lane-change blinkers. Dual exhaust was no longer standard on the convertible. The only way to get it was to order the "TNT" version of the 440 engine, an option that
