Hey Dennis,
If it has two round holes for speedo and gauges, and, if it has a mounting location to the upper left for a emergency flasher switch, its a 67-69 rallye guage cluster bezel for Cuda's with air conditioning. I'm guessing your Cuda wasn't equipped with air. If it doesn't have the flasher location, its for 70-71 Duster/Dart/Demon with Rallye guage option with air.
Best I can do with the pic provided.
