Having owned many E bodies for over 30 years, plus parting out several hundred over that time span and owing a few benchseat equipped models,...they only come one way, straight across the front, some were unique in having a hand/air pumped lumbar section, but most were just vinyl covered, available in almost all colors, the bench seat was optional in both the Challey and Cuda for 70 and 71 only,....very unique peice, as most new owners weren't interested in paying for a bench, when buckets were standard,...only choice of transmission was automatic, column shifted,...I know some pics of a 4 spd/customized benchseat Challenger were floating around moparts, but that was a custom,...nice touch though!
