The 747-400-style wing/body fairing was made standard for all 747 models from line number 704 in June, 1998 and on. It is also available as a modification kit. To further complicate your life, you ought to know that a small change to the dorsal (vertical) fin fairing was instituted on 747-400s from December 93 and on. There is a slightly differenct, but noticable change where the vertical fin meets the top of the fuselage. Again, this is also available for retrofit. Hope this helps Mike Lechnar Aircraft Performance Engineer "If I was speaking for Boeing, I wouldn't be doing it here."
