JimC Innovations QD adapter parts

Ive got a JimC Innovations QD adaptor that runs from m Ninja tank to my Drozd Blackbird and an internal part has fallen out rendering it useless. does anyone know if JimC is still selling Drozd accessories? Also If i can't fix it, can anyone recommend a replacement adapter? Here is a photo showing that there's something missing...
