PSR 8000 Cosmetics

Hey! My name is Pete. I’m new to the forums. I recently bought a PSR 8000 and of course, the shipper damaged the corner of the upper plastic chassis. Some of the pieces are there but I’m trying to figure out how to reattach, reinforce, and blend a coat of paint or plastic coating into the old so that it looks good. Any ideas would be greafly appreciated. Here’s a few pics:
