This is ugly, and not tested, but you can try something like:

in showthread.php find:

PHP Code:

eval("dooutput(\"".gettemplate("showthread")."\");"); 


Replace with:

PHP Code:

if ($forumid==*custom forum id number here*) {
eval("dooutput(\"".gettemplate("showthread_custom")."\");");
} else { 
eval("dooutput(\"".gettemplate("showthread")."\");");
} 


you'll need to replace [high]*custom forum id number here*[/high] with the forum you want to have a new showthread template displayed for. And create a showthread_custom template, Also you will have to do something like this for all the bit templates if you want more custimization.

if you want to do this with multiple forums, showing the same custom template, do this.

PHP Code:

if ($forumid==*custom forum id number here* or $forumid==*anthor custom forum id*) {
eval("dooutput(\"".gettemplate("showthread_custom")."\");");
} else { 
eval("dooutput(\"".gettemplate("showthread")."\");");
} 


or if you want multiple forums to display multiple custom templates do this:

PHP Code:

if ($forumid==*custom forum id number here*) {
eval("dooutput(\"".gettemplate("showthread_custom")."\");");
} elseif ($forumid==*anthor custom forumid number here*) {
 eval("dooutput(\"".gettemplate("showthread_custom2")."\");");
} else {
eval("dooutput(\"".gettemplate("showthread")."\");");
}
