Two 1977 Oldsmobile Cutlass 442 models play piggyback in an Arizona salvage yard. The 1977 models featured the ugly 5 mph bumpers mandated by the government. The muscle car era just a memory from the '60s, the largest engine available for the  1977 Olds 442 was the 403-cubic-inch Rocket V-8 making 180 horsepower. (Photo by Jim Prueter)
