Subject says it all, there are some kind of bolts on the bottom, but what are they? Should I pry them off or drill em out or what?

Thanks

 

After you get the inner door panel off, inside the door at the bottom of course, there are 3 speed nuts maybe 4.
I forget what size they are. But they'll come off with a deep socket. The two corners are just bolts. Very simple.
Lemme know how ya made out!

 

*C(-)ris understands now* So the brackets are part of the ground effects not the door. This shouldnt be too hard now.
