P.S. Soak the threads in penetrating oil (Liquid Wrench, WD40, etc) 
overnight before attempting to remove the screws. Consider replacing the 
screws with Stainless Steel with either  Hex, Allen or Torx heads, and 
coat the threads with Anti-Seize compound (available at your nearest 
auto parts store) before putting it back together for good.
