What all interior components from the 3rd gen will fit a 4th gen? On another thread I’ve seen that the dash and back seat are interchangeable, and I’ve been told that the carpet is as well. Can you use door panels from a 3rd gen? Or the inner quarter panels?

Is there any steering columns from other cars that will fit a 1973 nova? I'm really not wanting to go out and buy a 500 dollar steering column when I'm buying the actual car for 550! Hope fully I can just get a donor from another car....
