So the Prothane trailing arm bushings werent nearly as difficult as the front lower control arms. I ended up drilling a bunch of holes in the rear bushing, at the hub, then pushed out the bushing. The front bushing on the trailing arm was also drilled through many times, all around the metal inner sleeve. That was done with the trailing arm off the car. I used a bandsaw to chop the Prothane replacement bushing for the front of the arm into 2, so I wouldnt have to press it in. Worked great! No slop in the suspension, handles better than ever..
