That is good info that the flare nuts do not work well. The thule track is not long enough to span the predrilled holes for the factory rack. I will have to work on another solution than the thule tracks.
I have found a couple of aftermarket racks such as those made by
Gobi Racks
They seem nice but are much more expensive that the thule alternative. Does anyone have experience with other aftermarket racks for 4th gen 4runners?
