I'm not sure what you're asking about the center section. I've gone through my pics of the old trunk pan and don't see a difference. I've included a pic of the trunk with the old pan removed and the new support set in placeYes, I see that now, it`s a lot more pronounced than the factory one but easily fixed with my body hammer. I still need to know about the center section, I can`t compare to mine as it was cut out by a previuos owner either due to rust or possibly for mounting a fuel cell.
