Just put the same one on last weekend and I have the sport roof with headliner. Basically, rack to where the front two holes line up on the center of the front metal cross beam leadge. Once those two holes are mounted there will be a natural template to drill the rear two holes. I used a slightly smaller drill bit so I had to screw the factory hardware in. I figure this and silicone will provide a better seal. For the rear holes I used the factory silver screws and the front I used my own hardware. It's solid as a rock and have zero worries about it leaking.
