molding fasteners

I know this is going to be a tough one. There's a chrome molding which goes around the back glass and down to the tail lights. There are 8 fasteners/retainers along the roof line which I need. Along the trunk are just weird wire nut things which I can find online. I was going to fill the holes and go chromeless, Now I think I'd like to re-install when it comes time. So, I'm looking for the 8 plastic retainers:( The pic of the nice car is not mine, it's just to show the chrome molding.
