How was your experience with Thule 387. I was able to find 953 some how. I read somewhere that the gutters on the power roof are not the same as hard top. i am not sure what the difference is. Can you please share if your rack held up good. I am planning to just get the cross bar for a couple of kayaks.These are actually 953 gutter feet, which have been discontinued,and getting to be hard to find. There is a new style coming in october. Note that Thule mentions a max bar spread of 20 inches,on their standard height rack,for a 19 Jlu hard top,with 150 lb max load. Those rain gutters aren't made of steel,afterall. Hate to guess the cost of replacing something up there. A third crossbar might be a consideration if putting a basket up top.
I tried the new Mopar racks,which will work,if you don’t run the roof all the way back,but you run into spacing issues,and the clamp angle doesn’t fit the rain gutter properly. The rain gutter On the power top is a little different,than the standard hard top.
