Need 66 Barracuda rocker fasteners

I contacted Rick at Layson's and he said he hasn't seen this type of fastener. Anyone else? The larger "T" clip screws toward the top of the rocker to hold the top of the rocker trim. I can get those. The round fastener holds the bottom of the trim to the bottom of the rocker. The pin spreads the tangs out to hold the fastener in place. Three of the four tangs are missing on the fastener in the photo. The round hole in the trim is where the round fastener goes to hold it to the rocker. Nobody seems to know about these, and I need fourteen of them! 66 Barracuda guys please chime in!! Thanks FABO!!
