Rear Fascia Door
While looking at my 2005 GTO from the rear I noticed a plastic cover hanging down directly in front of the rear "GTO" fascia. I got underneath and learned there is a little door held up by 2 push pins. When I opened the door I saw 2 bolts coming through with 15mm nuts on them. Those nuts had almost back themselves completely off the bolts. I tightened them...what the heck do these go to?
I thought maybe it had something to do with the spare, but I think the spare is much further forward at a glance.
