If you are referring to the front sheetmetal it is all different. The '94 fenders are welded to the body while the '01 fenders bolt on. Hoods are different,01 looks longer but is actually shorter but on a steeper angle.Bumpers and brackets are different,and as Dave said frames are different.Steering box location/engine mounts and floor for the forward engine positioning. I have a 2000 and a '95,I prefer the look and feel driving the '95,it is more like my '77 Tradesman in driving feel.
