Interesting. The weather cover on mine is actually too large to fit underneath the radiator support. Whenever I put the headlight in, it mashes the hell out of the rubber. It's fine by me, though. It actually helps keep it in there.
Note that it may fit normally, but since I have DDM Tuning HIDs in there, a wire has to come out of the bottom, so it doesn't fit perfectly on the back. No problems with water getting in though (not a clue why)!
