1973 Dodge Challenger Base Apparel and Accessories by Legend Lines
For 1972 model year, the front of the Challenger was reworked including the addition of a new grille that extended beneath the front bumper, as well as new rear tail-lights. The options lists (both for performance and appearance/convenience items) had been drastically cut back. The convertible version (though a sun-roof was made available), most interior upgrade options (in particular leather seats), comfort/convenience items (in particular power windows and power seats), and all the big-block engine options were gone. The R/T series was replaced by the Challenger Rallye series. The Rallye model featured four simulated vents on the front fenders, from which exited matte black strobe tape stripes. As Dodge did not offer the Hemi or the 440 for 1972, the engine choices were down to three: the 225 cu in (3.7 L) slant-6, 318 cu in (5.2 L) V8, and a 340 cu in (5.6 L) V8 that was equipped with a 4-barrel carburetor, dual exhausts, as well as a performance-oriented camshaft and heads. All three engines were detuned to lower compression ratios in order to run on lead-free gasoline, and the horsepower ratings were lowered to reflect the more accurate Society of Automotive Engineers (SAE) net horsepower calculations. Each engine could be mated to a 3-speed manual or automatic transmission, while the 340 could also be equipped with a 4-speed manual if so ordered. The performance axle ratios were also gone except for a 3.55 sure grip which could only be had with the 340 and the heavy duty suspension. Toward the end of the 1971 model year a few convertibles were made with the 1972 front end (grille, lights, etc.) and rear end (tail lights and their panel). Sales were slow with less than 25,000 units being produced.
