If you look at the pictures I posted in this thread, it shows where the pushrod comes out, and other things to help. You mount the pushrod to the rudder servo, on the opposite side from the rudder. I didn't use a sleeve, I just put a Z bend on the end of the rod that attaches to the tailwheel, and an adjustable clevis on the threaded end of the rod at the servo end for adjustment.
