@betoney , Using a flashlight (or Torch if you're a Brit) so you can see what's happening, stick a long screwdriver in toward that left side/bolt head, and pry up, or pry down on the wire cluster just enough to find out which way has easier movement. Once you can move the wire cluster up or down enough to clear the bolt head, have a friend push it out from the right side. You'll literally have to pry the wires away for the bolt head to clear.
It's not your imagination; those wires don't want to move, but they will.
