Front Wheel/ Brake binding?

Lòoks good. I thought about a twin disc, as the threads are there on the RH fork. What did you use for the pivot arm, as they look to be handed for the LH side only?

   on the 500,the pivot is handed,but if I remember its only for the adjuster screw,when I fitted my 2nd disc I simply use a countersink drill bit to modify the arm,so the screw head would fit
