Abstract: An improved mounting system for securely attaching a piece of arcuate trim around a vehicle fender is disclosed herein. Such vehicle fenders have an inner edge that terminates in an upwardly directed flange, while the vehicle trim has a mounting flange nestable over the fender flange which further includes a plurality of elongated slots. The mounting system comprises a U-shaped strip of resiliently deformable metal whose opposing sides define a U-shaped recess for receiving the upwardly directed flange of the fender, as well as a fastener assembly for fastening the mounting flange of the trim to the clamping member that includes a threaded stud, one end of which is connected to a first side of the U-shaped strip of metal forming the clamping member. When the free end of the stud is inserted through one of the slots in the trim, and a nut is threadedly engaged to the stud, the mounting flange of the trim is secured to the clamping member.
