73 Duster - I didn't take it apart....body assembly questions

Not to sound rude but these cars are about as simple as they get I use to help some friends that had a classic car restoration shop they would get cars in baskets crates whatever some being only a few examples made or even proto types with very little information available and restore them
I hear ya, I am a brain surgeon, and retired rocket scientist, NOT a friggin Mopar resto expert!! lol
