Looking for an unobtainable spare part for my Tipo / Egea 2016 hatchback: one single side cap for original Mopar roof bars.

I've lost it during a trip but FCA parts resellers said they don't sell it alone, so I'm looking for ANY information about production sites and contacts where I could ask for it.

Thanks in advance

 

It looks like a Torx security socket would work for you. The socket will have the center hole, you can buy them with or without the center hole so make sure it looks like your fastener.
Good luck
