I started out with the fox FLCA, changed the ball joints but I found that the mounting point for the coil over using the existing hole created a clearance issue when the tie rod at full lock. I tried drilling a new mounting hole rearward in the fox control arm but found that the arm needed significant clearancing to fit the mounting bracket. I ended up buying a set from a forum member. I know there expensive but I would really recommend them.
