The same nuts up top above the rad support. Down below it fits pretty snug and tight. I think that the 97+ fenders have brackets that bolt to it as well for the lower, but it fits good. The main difference is the side markers, the pre-96 XJ side marker connectors are different than the 97+ so they do not fit entirely into the housing, but with how they are they fit snug into the side marker housing when it is screwed in. The hood lines up pretty much as close to perfect as you can get.
