I don't think you're going to find them. I searched for repro bezels for my 73 Dart Sport, and no one had anything for the later models. I ended up buying used bezels and have them reconditioned. They turned out great, but were costly when it was all said and done.
I wonder when the aftermarket is going to get in gear and start making more repro parts for A-Bodies? Right now, everything seems to be targeted to the high-dollar Cudas and Challengers.
