The steel ones aren't available anymore. you can order a new right hand safety lever from Stryker Ent or Midwest Gun Works ($5) or you can try giving Browning parts a call and see if they'll send you one.
The left side is fine because it is molded onto the metal bar that runs through the FCG. Right side just snaps on.
