there is an easier and cheaper way to kill both birds. both of my cars have had this done with no problems what so ever over 45,000 miles combined.
pop the rear hub loose from the lower control arm. elongate the holes the bushing bolt goes through by about 3/8"-1/2" toward the center of the car on both lower control arms.assemble loosely and push the bottom of the hub toward the center of the car. this will take the camber out of it and some of the toe. the rest of the toe can be done with the toe adjustment. torque to specs and your set. i did find on lowered cars camber bolts will still be needed, but this gives alot more adjustment range.
or for a couple hundred buy the ford racing adjustable subframe.
