Remove the nut under the left motor mount. Install the crossmember bracket supplied in the kit so that the slotted hole goes over the stud for the lefthand motor mount. Locate the pre-existing hole in the aft flange of the crossmember and align it with the other hole in the bracket. Install the supplied bolt through the end of the bracket and the aft flange of the crossmember. Tighten the motor mount nut and the bolt.
