Sagging Chassis?

[cwylie]

So recently bought a pro street 68 Camaro I am looking to turn into more of a modern pro street car. Durring the process of making the door bars removable I took the interior out. I saw I wrinkle on the tranny tunnel then realized the drivers door was stuck out a little at the bottom. Well looking further the passenger is as well and the door gap is a little tighter at the top than the bottom. The doors close fine though. Could the car be sagging in the middle? I find that a little hard to believe since it has a 12 point cage? Could it be from a wheel stand that he came down too hard on?
