It comes with everything you need to put it all together mine is a 2004 I made a couple changes but over all it works so I ordered other set for the other side
Moved 2, empty, 20 footer containers over 3 acres of grass and up a gravel hill. They worked exactly as intended, are in great shape, and I'm glad to have them if I need them in the future. Easy to put on and remove. I'm really pleased.
