So I recently purchased my 2004 6.0 in January. The PO had done the 2005 conversion grill. He also replaced the headlights however doesn't recall if the lights are 2004 or 2005. Are the lights the same? Or, because the grill has been changed to the 2005 style does it use 2005 headlights? Sorry if this is a dumb question I just don't want to purchase new headlights and order the wrong thing. (I'd keep the ones in it but the drivers side has moisture inside the lens and it's driving me nuts.) Thanks for the help guys.
