Just the t-stat. If I remember correctly, 1999-2002 used the water neck and t-stat.

Yea, I checked on it, the 2003 had the housing as well. In 04, they made the switch.

I ordered This one for my 05'. Hope it works. The description is a little different than the one andrew got, but I guess i'll find out soon.

FYI..you can use the stat only if you have a spare empty gooseneck, you dont need to spend the $40 for a one piece.
