My 73 dart had when new and {was redone the same way} loop Carpet on floor and wheel wells as well as the devider has plush,the inside of the quaters has plush glued to it.
the back side of the devider has plush, but the front side is loop so when the devier is folded down it matches the loop on the floor.
Also the back of the rear seat is loop.
I have step by step pics of when i redid it someplace Not only did they have a plastic cover over the rear tail lamps but they had early 73 a soft cover for the jack assy.
later years had a hard cover made of abs plastic.
