Looks like they used Malibu interior (seat covers, door panels and carpet) during the restoration. I don't know if the 300 Deluxe door panels are reproduced...
My 300 deluxe is sporting Malibu seat covers as well.... but still retains the 300 door panels and floor mat. I do have the original 300 seat covers in a box.... but are in serious need of repair... Here is a pic of my interior(ignore the dash cap [img]<<GRAEMLIN_URL>>/laugh.gif[/img] ).... note the door panels and the rubber mat...
