CSM series mounts are mounted to the seat bolts or seat rail bolts, whichever works best for your configuration. Some vehicles are not compatible with this mount. In order to know if your vehicle can accept this mount, carefully study the picture to see how the actual brackets look and where they are intended to go. Then check your vehicles bolting configuration. Sometimes the brackets can go between the seat rail and the seat. Other times the brackets can go between the bottom of the seat rail and the floor.
