I am removing the interior pieces from my 48 Chevy Truck and have come across some unique fasteners that I don't have a way to take out. It is kind of like a fat (regular) screw driver but the ends are closed and rounded. I was wondering if anyone knows where to get a socket drive or "screwdriver set" that I could use to remove them?

Thought I would ask before I start grinding down a set of screw drivers. Hopefully, someone knows what I am talking about, if not I can snap a picture tonight.


Thanks
