How to remove 1990 New Yorker door panel?

I got the following instructions:
"Unsnap the plastic appliques from the door pull strap and remote
bezel.Then pull the front edge of the bezel outward and push the bezel
backward to release it
Remove the mounting screws at either end of the pull strap and remove
it from the door panel
Not the installation angle of the window crank handle and then remove
it.To do this use an allen wrench to remove the allen screw from the
center of the window mechanism shaft
Remove the retaining screws from the lower side of the door handle and
remove it
There are spring clips mounted to the door panel which slip into holes
drilled into the door metal.Using a flat stick gently pry the panel
off the door at front back and bottom to release the clips
Lift the panel straight upward to release clips which retain it to the
inside of the door by running down into the window slot."

That's great, but there is a "Z" shaped bracket that attaches the door
handle to the door. There is a screw at either end of the bracket, one
attaching it to the metal door frame and one attaching it to the
plastic door piece. The space between the head of the screw and either
piece is not large enough to get a screwdriver down in there. This is
the only place the panel is still attached to the metal frame. Any
ideas?!?
