You'll note that the part I ordered to cover the hole isn't on the parts-list for my model of Honda, either. I couldn't find that part listed for my 2000 Accord. The page I ordered it from was for a 1990 Civic if I recall correctly. It didn't matter to me, I just needed the DIN-sized plastic cover plate. So I'm guessing that exact part would work for you, too.
