Which hook to use?

Thank you kh99, waiting forward...

Unfortunately it's difficult, I could write pages and still not explain everything (partly because I don't fully understand it myself). But in this case I happen to have a mod that changes the SHOWTHREAD template. It uses the showthread_getinfo hook location and has code like this

$find = "some string";
$replace = "other string";
$vbulletin->templatecache['SHOWTHREAD'] = str_replace($find, $replace, $vbulletin->templatecache['SHOWTHREAD']);

but, $vbulletin->templatecache contains compiled templates so it doesn't look like what you see in the template editor. That makes it tricky to know what you can search for and match. You could look in the template table in the database, the "template" column shows the compiled template. Or what I usually do is put in temporary code to write the cached template string to a file, like

$fp = fopen("showthread.txt", "wb");
fwrite($fp, $vbulletin->templatecache['SHOWTHREAD']);

Then I open that file in my editor so I can refer to it.

I hope that makes some sense.
