Hi guys, I may have a dead power steering pump on my 2010 GT500. Long story short, after swapping my P/S tank with a Shelby tank my P/S no longer works. Someone on another forum has same exact issue where we suspect the Shelby tank may be defective and ruins the pump. I have a buddy coming over tomorrow to help me troubleshoot my issue since he has worked on many mustangs in the past. That being said, does anyone know why the part # changes on a 2010 GT500 P/S pump from 2007-2009? I thought the engine and drive train were identical? The problem is I cannot locate a 2010 P/S pump ANYWHERE. 2007-2009 are available. Can anyone confirm if they do change from 07-09 to '10? Just trying to get ahead of this in case I do need a new one. Thanks all
