I know of "No Car " this old ,that has "All"of it's original parts. If you bought the car brand new and parked it for 40 years, I would say yes. Parts must come from other cars (junk yards, nos,etc.) Once an original drive train is gone, and you can't find it, your only legal option is from another car! A car can have (Matching Numbers) "VIN", and still have many wrong components.
