Tbars on the new Gen Rocket...

...Has anybody fitted Tbars or Windowbars to the new generation Rockets?...i saw a Rocket in the weekend that has this done and looks real nice. The guy who owns the bike bought it with this mod already done and so couldnt help me with any advice how to do it etc. They were drilled to take the internal wires. Here in New Zealand we do have 'The Handlebar co' who will make some to fit but im hoping someone can advise me of any problems fitting if there are any.
