Johnny mentioned that the trackbacks are a PITA, which he would know. What he didn't say is that the bloody torx screw on top is in there with loctite, and if you don't cook it with a torch or something first, you may be breaking tools and cutting that mother out. Please heat it up first, we put enough leverage on that part in the past that John started to lift the old ZJ a bit and it still didn't budge.
