69 Barracuda Dash Bezel

The plastic lenses can be separated from the bezel by heating up the edges of the previously melted tab while putting pressure on the lens from the back side. Some lenses just fall out when you separate the back. Take the lenses and clean them with warm soapy water. Using Mothers polish, carefully hand polish them using a soft non abrasive cloth. Baby diapers work great. You may have to repeat the process many times over, but you should see improvement. If they are totally fogged through, and polishing doesn't bring them back, then you can buy replacement lenses on several sites.
