I had a very similar install done on my Juke that used Thule's Top Track, which is a universal channel that can be surface-mounted on any vehicle and (probably) inset in the channels on the TC's roof. I paid $160 for the tracks and $60 for installation at Rack N Road, a local rack shop. It's been four years and it's been solid with no leaks or problems. They also pulled factory schematics to make sure there was no interference with airbags, sunroof or wiring. I'll likely go the same route again unless my TC happens to already have rails installed. This is a link to my rackventure...the walk-through is pretty universal.
