You need a radiator support from the newer model, headlights, grill, and maybe even bumper. Not sure about the bumper part. You need the lights, since the whole grill is one piece, even the part between the headlight, and turn signal. They swap on the 98-01 models, since the front end is the same, but 95/96 is the older style headlights.
