  They're tricky to pull but you can.  There's an expanding "v" which the
center
bolt expands against the side of the hole.  If you back the bolt completely
out
you risk dropping the "V" and the nut, if it's separate.  They're brass or SS
so you won't be able to pick them out with a magnet.  You have to fish in
there with a wire or screwdriver and gradually pry the "v" back together
more.
