Anyone have suggestions on a cargo box that's compatible with the OEM roof racks on an 89 XJ LDT (2 Door)?

Also curious bout the load limit for those OEM racks - I suspect it's not that high.

According to the owner's manual the roof rack capacity is 150 lbs. I have an '89 2 dr. Limited too. I use long "Pelican-like" boxes (about 44" x 14" x 7") on a simple rack that I built to attach to the OEM rack. Although not ideal you might be able to put these boxes straight onto the OEM rack.

Hey nice truck - looks familiar - same color as mine, except mine has lots of rust colored patina
