Welcome to the Team!
And I might add that there is no difference in the sheet metal once you are in front of the fire wall. All full sized Chevys used the same dog house (hood, fenders, inner fenders, radiator core support, and grill etc) whether a four door or a two door, sport coupe or sedan, wagon or convertible. All where the same sheet metal so any same year car can be a donor. If desperate and can do basic body work then you can look at different years and even Pontiac, Olds or Buick cars as a donor.
