The Murry B Park site does not list a part number, they list them as (1965-66 Chrysler, Dodge C-Body, and Plymouth Fury wagon pair of rear bumper guards with cushions, NOS). they are a step so would a sedan or hardtop have had a bumper guard with a step?. All the photos I could find of 66 T&C have the style like the ones in your photo so I dont know what these would be for but I dont see how they will possibly work. In order to clear the tailgate they would have to slide so far over that they hit the part of the bumper that starts to curve upwards. Its a shame, really like the looks of these.
