F.F. listen to JohnBuckner unless you have money to spend thats just burning in your pockets,Sheldons will take your $ if you want to spend it.
it's simple stuff mount one servo in its location hook the pushrod to the control arm.
mount other servo to other side of fuse oposite the other and hook up the other pushrod jsut make sure the servos are moving in the same direction if there not then flip one of the servos its simple really.
if your pushrod is too short then 1.25 will buy a new one you can rebend to fit.
buying a reversing Y connector,or a match box, not needed for this application .
