Mut: did you find that the chevy xfer case hung down much further than the IH one? I have had people tell me that doing the full swap was not too hard, but the xfer case hung down. In order to get your ground clearance back, you had to lift the Scout.
I was thinking of installing a lift kit anyway, because that is an easy way to get replacement suspension parts, and they seem to be cheaper in a kit than bought separately, but if I need more hight because of a drooping xfer case, I might go with a 4" lift.
