Many thanks for taking the time to reply, Thats just the information I was after. Regards, Jon

Hello, I wish to convert my standard Cub swinging arm, so that it is suitable for a 4.00 rear trials tyre. I have been told that I need to lenghten the arm by one inch, and widen it by one inch. I need to know how and where to cut, and how to weld it all back up. Has anyone got pictures, etc, of the details ? Thanks in advance.
