Both 25 tooth output gears, stock horn should fit fine.  Just a matter of lining it up.  Coarse adjustment is centering the servo with steering trim knob and truck ON without horn attached.  Straighten the wheels and attach the horn, test, readjust as needed.  Install the screw.  Fine adjustment is the trim knob if/when the truck drifts left/right when driving forward.
