generator case and fan pulley Delco Semi-gloss black....Aluminum end plates natural aluminum. Starter Delco semi gloss black on case, drive end housing and end plate. by 1958 they were several years into the stamped steel end plate with brushes made into the case but I have seen a few with an odd looking aluminum plate but not often. If you do have that aluminum plate it would be natural, steel End plate was black.
