Plastic parts that are ABS can be repaired very easily. I repaired several bezels on my 71 Barracuda this way and several grills. You will need some spare black ABS plastic, either from broken pieces or just buy a small piece of black ABS plastic on Ebay for a few bucks. Cut up the plastic pieces and put them in a small jar that you can seal with a lid, pour acetone over the top of the pieces and let the acetone turn the plastic into a gooey mess. Then just use the goo glue as I call it to chemically weld the plastic together. You can even make small tabs and stuff with it. The repair is strong as the original plastic and very easy to sand down and repaint. By the way, I tried the same stuff on a door panel and the door panel is not ABS plastic, did not work. Rod
