What you wish you had kept

As far as body sheet metal, I say anything that isnt rusty. I have a 70 Dart, and the lower valances front and rear are good pieces to keep, Fender extensions front and rear (70-72 dart) Doors and hoods, but they are big to store. Again as long as they aren't rusty. I know alot of sheet metal is available reproduction, but factory pieces are still better to have on your car IMO. Window glass just about everything lOL! If you are urious abot a certain part, look it up as if you were going to buy it. I think the repop valences are pricey.
