'70 Swinger Grille paint scheme

Ok, another question, has anyone got a good idea how to repair the broken bolt hole tabs that are common on these plastic grilles? Is there a plastic weld kit or tab kit for these? if not, I will have to come up with something. I was thinking riveting or screwing sheet metal tabs to the grille, but that may not be a good idea, I can see the rivets and screws ripping out of the plastic. Anyone re popping these grilles yet?
