Hello folks.  I have a hyster d6n winch mounted on a 977 20A.  I also have a hyster w6f winch I would like to swap onto same machine.  I don't have a coupler for w6f. W6f came off a d6d caterpillar.  W6f manual says coupler would be part number 196380 to attach winch to a d6. Manual only states d6. Not any model number besides saying d6. I  don't have a manual for the d6n winch.  My question is,  do any of you folks know if d6n winch coupler will attach the w6f. I checked allied website,  the do not list online manual for d6n that I could see.
