Can't get to that area from the taillight, HOWEVER.... take off the interior trim panel and you can get behind there. I used folding tie downs from a 4Runner and #12 sheet metal screws to anchor them in. You can reuse one of the existing holes that the folding buttons used.That's better than sheet metal screws just holding it in by threads. I would still want to reinforce the area. I guess I will remove the tail light and see what's going on back there.
