The trailer hitch thing makes some sense I suppose. The bolts are huge. I was thinking what could they possibly bolt on here that would require such big bolts? I mean the trunk pan isn't all that thick of steel. The odd thing is they seemed to have been there when the trunk was sprayed with the splatter paint. Almost like it came that way from the factory unless this trunk has been recoated at some point. I'm not sure if that area will be included in the section that I replace but those are getting deleted one way or the other.
