Vinyl top trim fasteners - looking for source

I found similar ones on eBay but threads did continue up to the head. I also need them for a Barracuda. Mine had a little plastic spacer/washer. Let us know what you find.
That's them!!! and yes about half the ones I removed had thin clear plastic washers on them, which promptly fell apart. I think they keep the trim itself from damaging paint/vinyl when installed.
