Not knowing how different they are, I'd set the winch on the mounting 
plate, mark the holes, then drill and tap a new set...if there's room. 
If not, make an adapter plate out of 1/4 to 1/2" steel or Aluminum with 
the original mounting holes off set.   Use large flat head 
screws/bolts.  You can off set the tapped holes up, down, right, left, 
or at an angle.  IIRC the bolts are half inch so you only need to off 
set by 3/4 to 1"
