Hey guys, I just bought an XJ this week and can't wait to take it to the mountains tomorrow. anyways...to my question. Unfortunately, it doesnt have a factory roof rack. It only has the two metal slides on each side that basically run the length of the doors and I'm not exactly sure whether cross bars go on the sliders or if roof rails attatch to them and then you attach the cross bars to the rails. I really hope this is making sense, because as I read it back, I am kind of confusing myself. Basically, I want to mount a safari style rack and I have no way of mounting it right now. I would post some pics, but I don't really know how to do that either. Any help you guys could give me would be awesome.
