Here's how I did it.

// +++++++ Super Close Thread Hack [ g-force2k2 ] +++++++
      $thread[newoldhot]='folder';
      if(($thread[open] == 0) OR ($thread[open] == 2)) {
        $thread[newoldhot]='lock'.$thread[newoldhot];
// +++++++ Super Close Thread Hack [ g-force2k2 ] +++++++

	// Strike-Through Hack
	$thread[title] = "<span class='locked'>$thread[title]</span>";
	// End Strike-Through Hack
      }
