Help me out here. (1)

So, I bought a Profile Design Carbon X bars from a friend and I would like to remount the arm rests and change the extensions to t2 cobras. I don’t have any trouble changing the extensions but the mounting of the armrests to my liking is what is puzzling me. I would like the pads to sit on the top of the bar and very narrow, much like the carbon 1.5 model. any suggestions?
