On the 03, The MPC Grill Guard fit together and on the condenser perfectly. The silicon is for the MPC, I used contact cement & pieces of old inner tube on top of the condenser. I did not have to drill any holes. The whole process took about 30 minutes, but I tend to work slowly. I also decided to get these after my tech flattened many of the condenser fins. When I mentioned it at the service desk, they reacted, as it was no big deal. I told them that kind of attitude does not fly well with me. Not much of a response on their part. The combo looks good and has the protection needed.
