robertchevy,
personally I think that a suspension lift looks better, but a body lift is easier. all it consists of is removing the old body mount bolts, adding the lift block spacers (usually 2-3") and reinstalling the new bolts supplied with the lift kit. you might need to alter the bumper brackets unless you dont care that the bumpers sit lower now that the body is lifted. There may be a few other small alterations like checking clearance on your fan shroud, but it is a pretty straight forward thing.
