To answer your question the 67 68 hood grille fenders and core support needs to be from a 67 or 68 the only difference in the hood is that 68 has a piece of trim on the lip , as far as I know the inner fenders are the same , also a note some dont think of is that 67 68 GMC hood and fenders will work also the 67 68 GMC core support will work too by changing to two headlight buckets
