double hood scoop hardware needed

Maybe this picture will help... Does it look as though someone has installed some sort of plastic anchor in there? I don't know what size the holes are supposed to be, but it looks like someone tried to repair some stripped out holes with drywall anchers(?)

I think I will need to drill everything out and install some sort of custom bolts; kinda like carburetor studs? ,threaded on both ends? Maybe some epoxy?
