Willys used two different sun visor brackets during production of Wagons, Trucks, and Delivery models. The early years were chrome plated and have a 3/8 diameter shaft that the sun visor sleeve pivots on. The Later years after 1960-61 also used this larger size shaft. From 1951 to 1960, the shaft size was 1/4 inch. 680184 fits this size shaft only, please check yours before ordering.
