To access the 10 mm lock nut, I took a shallow, cheap, 12 pt 3/8 drive 10 mm socket and welded a 3/8 steel 6 inch rod perpendicular to the drive end of the socket. Voila, a KKK waste gate adjustment tool. AND, the allen wrench can go through the socket to the adjustment screw to hold it while tightening the lock nut.
