70 Dart Grille resto (or any plastic grille)

being a 70 dart owner I have a few grilles in my parts stash of various driver quality. My question is what is the best way to re attach the plastic mount tabs?

and has anyone tried reinforcing with metal and pop rivets?

Over the years I have seen the JB weld,plastic weld glue methods but I am not sure that will last.

A common thing is to "zip tie" in places...

Thoughts? Opinions?

I do realize the plastic grille crowd may be a small group.:)
