My 83 T-Top Z/28 was tight as a drum when I ordered it new from the factory. It took just a few years for the rattles to start. Is this common to all Third gens or just the T-Top cars? I can jack up one corner of the car and can see the doors go out of alignment, so it definitely flexes. I'm really not sure if it's just the body, as I can hear the back hatch and doors rattle too. It seems like I can remember my wife's 82 Camaro 6 cylinder coupe not being near as noisy as mine when it was about the same age.

Yup, these cars are unibody cars. Body is part of the frame. They twist.

A fix that we all do and i think you must do are sub frame connectors.

Have your car taken to a shop that can align the frame. Then weld on the SFCs. You will be amazed...and it will be like you just bought the car again.

If you want to know where to buy these click on some of the sponsors to the right, i have the Spohn SFCs on my car and i love them.
