I just replaced a champion winch and replaced it with a warn.
The plate must be Rancher specific, and will have standard holes drilled. My champion winch only had two center bolts holding it down, my warn used the 4 standard bolts.
Also, if you have a fat winch, you will need to slightly cut one of the front supports. I ended up adding a brace up front to keep it sturdy.
This is my plate that was on the Rancher:
