I have a long drift, actually an iron workers alignment bar, about 15" long. I position a floor jack on theradius arm close to the bushing and the drift through the radius arm bushing into the floor cup, a push forward to align the two and a couple of jacks on the floor jack pushes everything home, total time once the jack is in place, 30 seconds top. I've used this system at least a half dozen times on mine and friends E's with never a problem, just make sure that the alignment bar is at the bottom of the threaded hole in the cup.
