Joseph,
The cuts are different between the RT and the GTS. The gts has a carpeted section that bolts to the rear upper console that helps conceal the cuts.
The RT does not have this part. You can if careful, cut the plastic of an RT so that it will bend around the bar and make a perfect fit around the bar where it passes through. I have pics on my website of OUR RT bar from the top.
I have a template at my shop that I use for installs. I do not supply templates as the car still requires measurements to be made as slight variations between factory fitment of the panels may require a .25" or so change in the cutting of the panel.
