1969 brought another major restyling to the Mustang. The Fastback 2+2 was gone - replaced by the new SportsRoof model. The new Mustangs were almost 4 inches longer than their 67/68 predecessors, yet they retained the 108" wheelbase of the original 64½'s. The base engine continued to be the 200 cubic inch six cylinder. New for the economy minded Mustang owner was an optional 250 cubic inch six. The base V-8 continued to be the 302-2V. The 351-2V and 4V entered the lineup for 1969. The 302-4V and the 390-2V were dropped, but the 390-4V remained.
There were two special engines offered for 69, the Boss 302 and the Boss 429. Both engines were only available in two limited production units, so called, the Boss 302 and the Boss 429. New features for 69 included quad headlights, front parking lights were now located behind the front valance panel, new quarter panel ornaments, side scoops and integral rear spoiler on the SportsRoof models, front seat back locks, and for the first time, the VIN number, in addition to being located on the driver's door, was also attached to the instrument panel, and visible through the windshield.
There were several new models offered during 1969. A little know model was the Mustang 'E'. It was basically a standard economy minded SportsRoof model with a six cylinder engine, a higher (lower numerically) ratio rear end with a large torque converter, and an automatic transmission. Air conditioning was not available on the 'E' model. A "Mustang E" insignia replaced the standard quarter panel ornament. Another new model was the Grande, which included the Interior Decor Group, an electric clock, special houndstooth check upholstery, and extra sound deadner. Another new model was the Mach 1 which was only available with one of the five larger V-8 engines. It featured special interior trim, special carpet, and high back bucket seats. On the exterior, the Mach 1 featured a low-gloss black hood, non-functional hood scoop (except models equipped with the 428 Cobra Jet engine which had a "new for 69" shaker scoop), hood pins, dual racing mirrors,special side stripe, pop-open gas cap, and dual exhaust ending in chrome, quad outlets. The Mach 1 also included the "Handling Suspension" and an additional 55 pounds of sound deadner and insulation materials. Another new model for '69 was the Boss 302. Built mainly to qualify the Mustang for the SCCA (Sports Car Club of America) Trans-Am series. The Boss 302 included a special 290 horsepower, 302 engine, 4 speed transmission, 16:1 ratio steering box, and a 3.50:1, staggered shock rear end. The exterior featured a low-gloss, black hood and deck lid, Boss 302 "C" stripes, front spoiler, flared fenders and Magnum 500 wheels with F60x15 tires.
All of the optional Mustang interiors were available on the Boss 302, however, most of them were equipped with the black, standard Mustang interior. The biggest and baddest of the Boss's, the Boss 429, was also introduced in 1969. Primarily built to satisfy NASCAR requirements, the Boss 429 Mustang featured a Semi-Hemi 429 powerplant. To compensate for the massive engine, the front shock towers were moved out one inch, and the front A-Arms were lowered one inch. The Boss 429 featured a huge hood scoop (the largest ever offered on the Mustang), front spoiler, flared fenders, dual racing mirrors, and F60x15 tires, mounted on chrome, Magnum 500 wheels. The interior featured the Mustang interior decor group, comfortweave bucket seats, and console. The Boss 429 also featured a competition suspension, rear stabalizer bar, power front disc brakes, power steering, engine oil cooler, trunk mounted battery, and a 3.91:1, traction lock rear end. There were a total of 299,824 Mustang's built in 1969. Credit for the above information goes to ClassicPonyCars.com
