Up for Buy-It-Now is a new old stock (without the box) fan drive pulley, Mopar part number 1615887.  This item was obtained from an old service garage and is not a newly remanufactured part.  According to my Mopar Manual, this is used on the following models and years:

1955 Plymouth...P27 Plaza V8, Belvedere V8, Savoy V8, without Power Steering and without Air Conditioning

1955 Dodge...D55-1 Coronet V8, without Power Steering
1955 Dodge ...D55-2-3 Royal V8, Custom Royal V8, Royal Lancer V8, with and without Power Steering

  This is a one groove pulley with a 5 11/16" O.D.  It is in brand new, never used condition and shows no indication of ever being mounted or installed.  It is still covered in a light coating of grease from the manufacturer.  There are a few spots of light surface rust on the piece from many years of shelf storage.  May or may not need a light polishing up before installation.  There is an original Mopar pats tag attached, however it is very brittle and ready to come off.
  Please feel free to E-mail me questions.  International bidders are always welcome.  Thanks for looking!
