OK, is that $70.87 for both of them as in each or really both of them? Any new directions for this mod, or if I do a search will your directions come up? I know there has been some discussion on this topic here over the past several months - just want to be sure I have all the info, because this is next on my list (although I should have done it this winter!). I guess you are using the 4WD Auto switch to turn TOD off and on, and the 4WD switch to lock 4WD high? Any problems/concerns with this arrangement?
