I have these Fat SS bars installed also. I used the template and instructions that Squirrel Crusher provided for me(thanks again)and it worked great. I will mention that even w/ the template and additional careful measuring, I needed to trim just a small bit of plastic around the holes to get them in, and a nice no rub fit. This is what the rubber escutcheons cover up for you; so there is a little wiggle room. My take on the "Cosmetic Only" statement is that the manufacturer is just covering there a$$, because they are not OEM. These bars are thick, heavy SS and are tig welded w/ beautiful full solid welds. I believe they are every bit as strong as the OEM, if not stronger. They bolt up exactly like the OEM, so why wouldn't they be? I installed them in our Coupe because they look simply bada$$, and gives me a place to mount the GoPro. Not going to be as strong as a real racing 6 point rollbar obviously, but a nice little mod.
