Was the non LS front air splitter installed at the factory or at the dealership? I ask because when I changed the oil today I noticed that several of the plastic push nuts (not sure what there called) are missing and the holes appear to have been hogged out with a drill. Leading me to believe that a lazy shop mechanic didn't want to mess with it, got out the drill to align the holes.

Rick, it is installed at the factory but not sure if on the line or at VPC. You should let the dealer know about it in case you have any problems.
