Im not sure. But I have a gutter mount for the Rhino racks on my ute's canopy with the track mounts installed additionally (not a cheep setup) and it works a treat. Personally I would be worried about mixing the sets up to save on dollars, I would hate to hear the ripping sound as racks and board let go



When the funds permit I will be looking at installing the same system to the ute's roof as well.
