Locate the steel E-Drill Bushing provided in the kit. Insert the E-Drill Bushing into the VA-146 Elevator Center Bearing. Match-Drill #17 the WD-605-L-1 Left Elevator Hom using the E-Drill Bushing as a drill guide.
Remove the left elevator from the horizontal stabilizer. Final-Drill the hole in the WD-605-L-1 Elevator Hom to 1/4 inch and deburr the hole. Repeat steps for the right elevator.
Install both right and left elevators to the horizontal stabilizer. Secure both elevators in the "trail" position by placing strips of duct tape over the gap between the elevator counterbalance arm and the horizontal stabilizer.
With both elevators in the "trail" position there will most likely be a mismatch in position between the bottom end of the WD-605-L-1 Elevator Hom and the bottom end of the WD-605-R-1 Elevator Horn. Identify which of the two elevator horns is the most aft.
In the most aft WD-605-1 Elevator horn, locate and drill a 3/16 inch hole. Measure the spanwise distance between the WD-605-L-1 and WD-605-R-1 Elevator Horns.
Insert a 3/16 bolt through the hole drilled in the WD-605-1 Elevator Hom. Place the Drill Guide Block against the elevator horn with the bolt passing through the hole drilled per Step 9. Clamp both elevator horns together with the drill guide block between them then double-check that both elevators are aligned in trail.
Remove the 3/16 bolt from the WD-605-1 Elevator Hom and Drill Guide Block. Match-Drill #12 a hole in the elevator horn using the elevator horn and drill guide block to aid alignment. Drill the hole as straight and as square as humanly possible. Deburr the holes in the elevator horns and set the elevators safely aside.
