Use the video Roelof on Xray Clutch help you had thre other thread you composed.
Salven's video I been useing for 15+ years or so or when Serpent introduced the Centax.. Easiest way to set up the gap or endplay. Measuremnt calipers are available for cheap.
Just follow the steps on Salven's video.
Sorry a different composer of Xray Clutch Help. It doesn't matter which engine manufacture you have.
