If you are looking for aftermarket parts for the MT2
New Era makes a rollbar for the MT2. Their URL is

ARO makes aluminum shock towers, 14mm wheel hexes and is working on aluminum diff cases for the MT2. To contact ARO, do a search on user 'Dr Honda' and send him a PM. He owns ARO and posts here.
Edit - I did the legwork for you. Here is Dr. Honda's page. Send him a PM and see what he has and prices. I highly recommend his shock towers, they are fantastic!
