The lift will be a body lift, everything is lifted via blocks, above subframes, extensions on the struts and tranny lowering blocks, an adjustable pitch stop rod will be included and an extended steering shaft. For which by the way there will be a $25 core charge on the steering shaft (those puppies are expensive). As for the difference in lift designs 03/04, the lift will be a direct replacement for either model, for example in the 04 you will take your old lift out and replace it with ours. Here is a link to our website there is a picture on there of one of our EA lifts http://alliedarmament.homestead.com/LiftKit.html
(this should give you an idea of what you are going to get except that your lift will have about six more components).
