dimmer switch nut

[comanche32]

somehow ive lost the nut that holds the dimmer switch in. wondering if theres somewhere I can find one without going to jy. if I have to go to the jy will the xj and mj interchange thanks

xj/mj are interchangeable,

unless you find a sleved nut with a flat head slot cut into it i think your off the the j/y
