How do you remove D1 mud flaps?

[Tugela]

The rear mud flaps on a D1 are sandwiched between 2 metal plates and secured with 3 pieces of hardware. How do you remove the hardware? On the one side there is a cylindrical nut, for lack of a better term. The head of the bolt that connects to that nut is flat, flush, and blank. Neither end of the hardware appears to have any feature to which to attach a tool. I tried turning the cylindrical nut with vice grips, but that just spins the entire assembly. What's the trick?

Take it off road for couple miles.

Sounds like a similar setup to a D2. A drill or grinder may be your best bet

That's exactly how I removed the one side. Now I need to get the other.

I cut mine off w/ a knife. The rubber is still lodge in between the rivets and metal but nothing shows

They were some type of rivot on mine. One side broke free and the whole thing was hanging at an angle.

I drilled out the rivot, pushed the rubber flap into the sandwich spot and secured it with a bolt....

Drill it out or grind it off

What a stupid design. Oh well, out come the medieval tools of destruction.

I used a grinder for mine

It's a simple, cheap design.
