Honda-SOHC

Hi,starting to build my CR replica, final problem is the modification required for a brake plate, I have good pictures to guide me but have not got the cam levers required to make it authentic looking, I would need the arm which has the spindle for the cam half way up it, rather than the spindle hole at one end, I require a fitment for a connecting rod at one end and a facility for a cable at the other. Any help would be appreciated.
