I've been slowly accumulating parts for my '65 resto for some years. About 10-12 yr. ago I ordered a new repro grille. It was unsatisfactory--all kinds of machine marks from the tooling, and i sent it back. A couple of years ago I ordered one that was a genuine GM (NOS I guess). From Modern Chevrolet in Winston-Salem, NC I think. It was fine and price was OK. I think you can still get a new GM grille for a '65.
