Correct 1/2 year 1600 pump- Shaft protrudes thru the metal 4-blade fan for 67.5 only.
 
Fan fasteners included.  Heater fitting available separately.
 
Careful what you buy on Ebay, there are all kinds of cheap and incorrect pumps out there.  
 
Cast Impeller- excellent quality pump!  Not GMB or Aisin or other ebay junk!
