Htaccess Url Forwarding on Uninstall

Hi, I need to uninstall vbSEO on one of my forums but am having trouble with the htaccess to go back to the old url's

My settings were:

Forum: [forum_title]-f[forum_id]/
Thread: [forum_title]-f[forum_id]/[thread_title]-[thread_id]

I have tried:

RewriteEngine on
RewriteRule [^/]+-f([0-9]+)/[^/]+-([0-9]+) http://www.domain.com/showthread.php?t=$1 [L,R=301]

But that is giving me the wrong thread number...it's taking the forum id for the thread number instead .. and since I only know small htaccess stuff through google I don 't know what to change to make it work right LOL

you need to use $2 instead of $1

Awesome, thanx SO much!
