I bought a rack off craigslist for 50 dollars it came off a 98 xj for my 90 xj but the rails were completely different.. But I don't really know what kind it is and I was hoping that maybe there was an adapter kit I can buy or maybe a different way I can mount it.. If you know what kind it is or have any ideas feel free to let me know

 

It looks like gutter mounts. Is that right?

 

No the mount to the rails but the rails from a 98 are entirely different
