Hi, just wondering if it is possible to fit the door panels (front, rear, or both) from a 1991 300E into a 1989 260e. Also, is it possible to fit the door panels and/or rear seat from a 1994 E320 into the 89 260e? My rear seat is sorta falling apart beyond repair and as far as the door panels, the newer door panels just look much nicer. Thanks for any info guys!
