'47-'55.1 Chevy COE's have the same bench seat as the conventional cab big trucks and the pickups. They use a linkage system, that attaches to a shfter mounted to the center engine cover. '47-'55.1 GMC COE's have a full seat back cushion,but have separate driver,& passenger cushions,with the shifter coming straight out of the tranny, up between the seats.I'll send you a picture of my GMC COE seats tomorrow.
