Tiger, in your example, you'd put the cutouts for the rudder either above or below the elevator cutouts. Doesn't really matter where they are as long as they don't interfere with other linkages. It is however common to run the rudder cutouts well above the elevator cutouts... often very high on the fuse, i.e. above the stabs. This also helps center the pull/pull linkage on the center of the rudder.

I have a pic, not the best, but see the black spot on the rudder... that is the control horn mount. If you look closely at the fuse right before the fin, you can see the fairings that protect the pull/pull exits for the rudder lines. They are very high on the fuse.

Cheers
