Does anyone run that $699 pre-fabbed cage in their XJ. Ive seen it in the back of a few magazines and wondered if their was much to it, or if it bolted or welded in somehow. Could you cut the roof off an XJ and run that cage ok? Any help would be greatly appreciated because this seems to be the cheaper option for me considering my current status as a full-time student. I'll see if i cant find that ad when i get out of class and post this up with a name unless someone knows what im talking about. Thanks.
