24 in the same was as the inside swing arm 20 except a roller 28 is placed on both ends of the pin 26 then one side of the inside arm 24 lays flush and is connected to the tailgate 11 the main arm 18 has an upper flange 30 that extends from the top of the main arm 18 towards the tailgate 11 and a lower flange 32 that extends from the bottom of the main arm 18 away from the tailgate 11 even though the upper flange 30 and the lower flange 32 extend towards each other they do not come in contact thus creating a track on the main arm 18 that contains the rollers 28 similarly the inside arm 24 has an upper flange 34 that extends from the top of the inside arm 24 towards the tailgate 11 and a lower flange 36 that extends from the bottom of the inside arm 24 away from the tailgate 11 a track is created on the inside arm 24 by the upper flange 34 and the lower flange 36 extending towards each other but not coming into contact with one another the inside arm 24 track contains the rollers 28 the main arm 18 and the inside arm 24 are positioned such that the tracks created by the flanges 30 32 34 and 36 are facing each other an upper carrier plate 38 is placed between main arm 18 and the inside swing arm 20 and the outside swing arm 22 in order to maintain the spacing between the main arm 18 and the inside swing arm 20 and the outside swing arm 22 the pin 26 that connects the main arm 18 and the inside swing arm.
