Had the 4 18 mm bolts and three clips to get to the speakers. Of course one bolt did not want to come out but that is normal. Otherwise pretty easy except Detriot doesn't mark positive and negative so I had to guess to get them wired right and in phase. After that they sounded great.
Under the Duh category I lost one seat belt bolt. Could not find it anywhere until I realized it was stuck to the magnet of one of the old speakers already in the garbage can
Thanks again to all who helped me out. Loving my GP!
