I just bought an immaculate 2006 330RX. When I went to change the oil, the screws, pop rivets, push pins, etc. were apparently put back in incorrectly. I have bought all the fasteners needed to hold the under engine splash guard and at best would be guessing what goes nwhere, except for a few screws because it is evident by the threaded frame part. Can anyone there help me figure out where goes what? Thanks for reading this.
