The swap to discs is easy, go discs, much better...
If you want the easy way to swap to discs, get yourself another passenger side outer brake hose, and two of the nuts for the hard lines, cut the hard lines where the stock line sits on the top of the pumpkin, stick the nuts on the lines and crimp the lines for them, install on stock center drop line. Of course I think the stock Explorer setup works too, but I wanted more than 3" of down travel on the drivers rear tire...
