Abstract: A mounting system and a kit for installing an accessory on a vehicle are disclosed. The mounting system has a base including a foot portion and a first interface portion. The base defines an axis extending through the first interface portion. The mounting system has an interchangeable swivel member including a second interface portion and an accessory portion. The first interface portion and the second interface portion being configured to selectively engage each other in a first configuration and a second configuration. The mounting system has a resilient connection assembly configured to resiliently connect the interchangeable swivel member to the base. The resilient connection assembly includes a biasing element configured to exert a biasing force to axially bias the first interface portion towards the second interface portion.
