Mercury replaced the Montego, as it expanded the Mercury Cougar nameplate to its entire intermediate model line with the Cougar XR7 becoming a direct counterpart of the Thunderbird. Design overview Chassis The LTD II uses the body-on-frame construction shared with the 1972–1976 Torino/Montego. As with the LTD, the LTD II used a full perimeter frame; to isolate road shock from the body, the frame was fitted with 14 rubber body mounts and five crossmembers. On the rear suspension, the four-link solid rear axle used coil springs. The LTD II carried over much of its powertrain line from the Torino, with one exception; in the interest of fuel economy, the 460 V8 was dropped from all Ford and Mercury intermediates, with the 302 V8 making its return as the standard engine (outside of California). As options, Ford offered the 351M V8 and the 351 Windsor V8, with a 400-cubic-inch V8 serving as the largest engine offering. For 1979, the 400 V8 was discontinued. Body Although the transition from the Torino to the LTD II is theoretically a midcycle update, Ford stylists made several styling changes to introduce the new model line, moving away from the Coke-bottle styling that dominated the exterior of its Torino/Montego predecessor. All body styles (including wagons) featured frameless door glass; the 4-door models had a thin, fixed "B" pillar. Like the later Torino models, the LTD II coupe lacked a fixed "B" pillar, but the rear quarter windows didn't roll down, making this model a coupe rather than a true 2-door hardtop. Though limited funds precluded a complete redesign of the exterior, the roofline and all sheet metal from the doors rearward were given an extensive update. Adopting much of the design language of the redesigned Thunderbird, the roofline was given larger, straight-edged windows (including optional opera windows) and a level beltline, while the body retained relatively large fender flares. The LTD II carried over the use of the Elite's hood and modified front fenders with a restyled front end panel adapting vertically stacked rectangular headlamps and a new grille. The rear end adopted styling elements of the full-sized Ford LTD. Due to the cost of redesigning the rear quarter side panels, the LTD II station wagon was produced with rear doors and rear quarter panels unchanged from the earlier Mercury Montego line; the station wagon was discontinued after 1977. The LTD II was produced in three
