PK125 Forks - Front Brake Adjuster (like T5/PX)

I'm putting a set of PK125 forks into my PK50 - They have the drum brake adjuster, similar to some of the T5 & PX's, with an adjusting wheel on the arm, but all thats on the Hub is the arm. I know I need this: 17964100 - Adjusting nut frontbrake PX/EFL/T5/PKXL2/Rush/N/FL. What else do I need to connect the brake cable up?
