Door Filler Panel Fastener Question

[signsup]

Picked up two M998s, one a two door and one a four door and one runs and one does not and I want to switch the body panels around to get a running four man soft top. Anyway, the two rear door filler panels are held in place with a slotted fastener that uses the rear seat back fastening system, but also four six sided fasteners that stick out of the front of the panels and connect into the B pillar, I presume, maybe just the body skin.
But I have no small sockets that are the correct size for these unique male fasteners. Do I need a special tool? Or can someone direct me as to how these are removed?
Thanks in advance.

The rear one is a 1/4 turn Dzus fitting and the front screws are 12 point (IIRC), I don't remember the size but they are U.S. that panel is screwed to the threaded holes where the rear door hinges will go.

Yes, it is the 12 point size that I need. If it is not a special tool, thn I need to purchase a 12 point socket and don't need a whole set. But...if I have to, I have to. All my 1/4" drive sockets are six sided and I can't find one that grabs without slipping and I don't want to round these over.

I used a 1/4" box end wrench and they came off. I'll pull the hinges off the other M998 and mount them in preperation for the soft doors. Maybe this thread will help the next guy.
