Our bracket should work on most after market chopper forks, or with our fork legs which have 30mm diameter part #513038.   If your forks have smaller diameter legs you can use any material like a strip of tape to build up the gap to use the clamps. Installed, there is up to 5 1/4" between the center of one adjustable width bracket to the other to adjust and fit your fork's width.  Included is an "L" bracket" which can be used or not used depending on your application.
