I'm trying to find replacement screw grommets for the vent in the D pillar. I have gone to a local auto fastener outfit who deals directly with Auveco products and came up with no replacements for this plastic screw grommet. It is a 5.5mm square hole, see image, that it goes in and I did find a 6mm for a Ford but I'd rather not modify something to work it just seems easier to snap the right part in. I'm certain I'm not the first person who has the need to replace these so I hope someone here has a source to acquire these. Any help would be greatly appreciated.
