what you need to look at is ; your fuselage rear section has 2 exit slots 1 for rudder and 1 for elevator and you have 2 servos up front for these. lets say the elevator servo is on the right hand side as so the elevator exit to linkage, if you have problems of some contact you can move the elevator servo to the rudder servo side and do the same for the other , this will like a criss cross but just make sure you have easy movements to both servos / rods, it doesn,t matter if the dowels slightly touch each other but make sure the steel rods keep clear of each other [ interference ] just take your time and you will get it right.
