I've had this for a couple months now, and love it!
It's 39 x 44 x 6½" (99 x 112 x 16.5cm), and also has an extension available if you can find it.
The brand is Sportrack, made in Canada. Sold at Canadian Tire. It comes with the fairing, and I also bought the net that goes along with it. I'll be making up a bracket to bolt down my oversized spare soon.
I also cut two holes in the fairing and mounted two old lights I had. Since they're driving lights, they don't really work so well on the roof. I'll probably buy flood lights for the rack and put the driving lights on the bumper at a later date.
I wired the lights by running the wire through a rubber sleeve (long heatshrink I got from work), and I ran it down the passenger side of the windshield, down under the hood to the battery. I then wired a relay and a switch that went from the battery through the driver side door, up through a rubber grommet that was in the side of the A-pillar (the metal column on the side of the windshield), and down into the dash.
pay attention now, here comes the custom modification part...
I did have to reposition the factory cross bars to be able to line with the cage. Pretty simple. Just pop off the side rails cover and unscrew, then take off the cross rail and flatten out the metal tabs that fit into the limited number of holes. This allows infinite adjustment on the factory crossrails.
