For sale are dash heater defrosters bezels. These are going to be way better than original style ABS plastic that are injection molded. They will never get brittle on you. I am making them out of ASA... (Acrylonitrile Styrene Acrylate) is a durable, weather-resistant thermoplastic similar to ABS but superior for outdoor use because it resists UV light, heat, and impact without yellowing or degrading, making it perfect for functional parts, automotive components, and enclosures needing strength and longevity.
These are very nice bezels. You can also sand and paint them any color you wish. I can create them in black or white. These will work for any 67-76 A body mopar. Also, these are sized down to match the exit hose sizes from the heater box. One side is 2", the other side is 2 1/4". So no need for hose reducers any more. Just straight hose to and from your heater box!
