Wrong on price. Just got charged $45 plus tax for one side at a dealer. Would you believe someone stole just one on a recent trip to California? Might be worth shopping around.
The roof rails are attached to welded studs that are a bit too tall for the trim to fit over them. You may be able to remove just enough to make the trim fit and still be able to reinstall the rails down the road. I didn't bother trying, just Dremeled them off altogether. I might have tried had I had my hands on the trim at the time but didn't care that much. They just add aero drag and about 20 pounds, and I've managed to survive my entire life so far without the slightest desire for roof racks (in part because I always go for hatchbacks).
Personally, I think the car looks better without them.
