Hi - first post to this forum - been trying to find a "genuine" solution to this issue for some time as well - even more complicated as I am in Australia and SRT and Mopar America havent bothered responding - i sent a link to the autoweek story and Mopar Australia responded that they do hav a "new" solution though I havent seen it yet. Not particularly interested in putting Grand Cherokee rails on my SRT - and have to plug holes etc whilst not being sure there are enough bolts holding it down whilst carrying, surfboards, sailboards, mountain bikes etc - skis are probably not such a big deal.
Anyway - there is a Mopar number for the racks in the autoweek article - described as being provided by Mopar /Thule - it is a roof edge grab system and is pretty chunky/ugly - though this could be a good thing as it does mean I wont leave it on the car too long between uses. It is a non standard part and NOT available through Thule dealers in Australia.
Not sure on putting up vendors web sites here -PM me if you cant find just with the part number - Google seems to pick the two places I found them. now if only they would post to Australia.
