Put on cnc levers. Found the clutch already had a threaded adjustment nut opposite the cable adjuster. On the plus side, they fit. They were sold as fitting two versions with different brakes.
Each newer design seems to get worse. The adjustable plungers sucked. But the new one recesses into a rotating barrel inside the perch and it will mount miss-seated. Lining up for the pivot bolt was very difficult for some reason.
