Beam - I can speak first-handedly on this. I had J&J Reproductions stamp my barracuda & shaker cuda fenders. I drove both sets to him & picked them up a week later. You'll prob ship. They live in Monroe CT. It was 2 1/2 hr drive for me, but well worth it. He advertises in MCG. It's a father & son business.. his name is Jeff.. really a cool guy.. owns a 71 droptop.
They have the same die stamp that chystler used. The stamps have the recessed holes that math the gill flanges perfectly. If you look at an org cuda gill, one side is slightly wider than the other. The recessed area fits that EXACTLY. He charged $400.00 per pair. No cutting or torching. I would highly recommend them. I can't speak for anyone else. I would never cut in those gill plates I've seen.
