Hi PEI. If a fresh part proves unavailable, take the busted one and the intact opposite bracket to a decent local machine shop. Shouldn't cost to much. The aluminum in your piece is too weak for that job. Replace both sides. Although, the nearest KTM or Husqvarna shop can replace most of your bike. Try them.
Those brackets don`t get much loading, if the axle is correctly tightened. You sure all spacers are the correct ones?
