I looked at mine again last night. My reciever is only about a half inch below the bumper. It is also recessed about an inch back in under the bumper. Very hidden, and I couldn't be happier with it. The orginal stickers are still on my hitch, so maybe I will look for model number, manf date [purchased 2002], or something like that. The only thing I can think of is that the 98 and 99 had different holes in the frame. If so, I would think Hidden Hitch would make different hitches for each year. They don't.
